Preferred wiring harness
 

What is the best option? I had a painless but sold it.

Re: Preferred wiring harness
 

get another one. why get rid of it?

Re: Preferred wiring harness
 

I have a Painless in my truck and I have a painless in my race car also. They are not the cheapest for a reason. They are nice and well thought out.

Re: Preferred wiring harness
 

I'm happy with painless. Summit Racing had the best price when I bought. Part 10206.

Re: Preferred wiring harness
 

Have been using M&H wire harnesses all along.
All plug and play OE style, and the customer service is very good.

Re: Preferred wiring harness
 

I have the American Autowire Classic Update kit. Check all the websites for the above kits and this one, then do the reviews.

Re: Preferred wiring harness
 

M and H or American Autowire are exact duplicates of OEM and are plug and play. Don't waste your time with anything else.

Re: Preferred wiring harness
 

M and H is too expensive for me. Has anyone used EZ wiring harness here is a link
http://ezwiring.com/wiring_harness.html, I am looking at the one that is $185.

Re: Preferred wiring harness
 

I'm having a Keep It Clean harness installed in my 67 currently, because thats what the guy doing the install asked me to get.

Re: Preferred wiring harness
 

I have a Painless...it wasn't. They don't tell you, until you open the box and read the instructions, they don't supply all (some but not all) of the factory plugs or bulkhead grommets and the headlight portion of the harness is split at the headlight plugs, needing to be "butt" splice connected, crimp connectors supplied by them. I am not a fan of "butt" splicing. Soldiering and heat shrink tubing is the only way to go.
I got a good deal when I bought it from Summit. I think I paid $365 and Painless was giving $100 back.
I spent an additional $100 - $150 on other wiring supplies: heat shrink tube (four different sizes), nylon braided wire loom (two different sizes), several sizes of nylon wire ties, grounding kit from Summit/Ron Francis (ground buss, heavy braided ground strap and misc. ground wire), several (four) relays and several (6 - 8) watertight connectors.
Don't skimp on dedicated grounds for all of the different devices in your electrical system, individual lights, alternator, gas tank fuel level sender, radio, air conditioner...you get the idea. If you have a goofey electrical problem, it's a ground.

Re: Preferred wiring harness
 

I used EZ Wiring in my project truck and liked the kit, considering it was a universal kit. For a universal kit and the money it costs me, I thought it was great. All wires were labeled and I had plenty of wire length for each section going to the front and rear. It did come with the plug for the column also.

I have never used the Painless or American Autowire so can't comment on those, although I have heard good things about them.

Re: Preferred wiring harness
 

Do you guys sell EZ Wiring? If so PM me a price please.

Re: Preferred wiring harness
 

I have an E-Z wire kit in our hot rod was good quality .and good customer support.

Re: Preferred wiring harness
 

I'm using american auto wire in my 72 if i can do it anyone can def a good choice

Re: Preferred wiring harness
 

I am usally a believer in you get what you pay for but I am leaning towards the E-Z harness due to price.

Re: Preferred wiring harness
 

I had a painless and sold it because my factory harness is in good shape. What I have learned from my LSx swap is, there are not enough additional "ignition on" circuits in the factory harness. I would like to see a harness that contains all of the original circuits with additional circuits for fuel injection equipped trucks. I like the way Ron Francis kits are not pre-terminated so that you can install only what you need. With the 18 and 21 circuit kits you end up with extra wires tucked all over the place. Seems to me there is room to improve what is available for the after-market.

Re: Preferred wiring harness
 

I used the american autowire in my build, great quality and service, much better than the painless imo.

Re: Preferred wiring harness
 

Board member Wes, at Classic Heartbeat, got me the M&H harnesses and beat the prices that M&H has posted on their website. Give him a shout.

Re: Preferred wiring harness
 

I called and spoke with them since they did not list a kit on the site. The guy was not helpful and told me I just need to price each specific harness off the site and it supposedly cost $800 plus. Since he didn't want to help I didn't persue it any further.

Re: Preferred wiring harness
 

??? Wes, who is the owner, is probably the most knowledgable and helpful guy on this site. Please dont judge him on one call.
Btw, I got my AAW Classic Update kit from him, its great. Plenty of extra circuits for whatever, as well.

Re: Preferred wiring harness
 

I did not call Wes I called M & H. I have nothing bad to say about Wes.

Re: Preferred wiring harness
 

No, unfortunately we do not sell EZ wiring. Just American Autowire & Painless.

Re: Preferred wiring harness
 

M&H is the manufacturer... They will be the first ones to tell you that they prefer you to buy from places like Classic Heartbeat, they will not be selling the product cheaper than their distributors.

Re: Preferred wiring harness
 

I realize there are a lot of companies that price things higher than a distrubutor but the guy just didn't want to help at all and shot me a price of $800 and something.

Re: Preferred wiring harness
 

Get the AAW Classic Update kit from Wes. You will thank me.

Re: Preferred wiring harness
 

dont worry about the low cost .I work in a hot rod shop and have seen several wire kits.if you lay most of them next to each other you cant tell the difference. we used to use american wire, but now we use E-Z with no problems.

Re: Preferred wiring harness
 

Well like some have said in the thread. It depends on your skills and if you want to cut your firewall so the harness fits. We sell exclusively M&H and American Autowire because they are the best on the market! Hands Down! They fit perfectly, have exact looms and plugs and use the same color coding that GM did. Their classic update kits for the guys with electric everything love them also, because you don't need in-line fuses to protect your parts. The kits have the fuses built into the fuse panels. I have rewired several trucks from 1955 to 1972 and I do not have a complaint one about them. Well mayby I complain about laying on my back to wire under the dash..lol oh and I didn't understand one of the schematics of the classic autowire updated wireing kits. (however M&H was very patient with me while they explained to me what I wasn't seeing in the schematic.) So I would buy what you want to buy, but beware that some of the kits being pushed in this thread require you altering your truck to make it fit and require you using some of your old parts. M&H nor American auto wire will require that. WES

Re: Preferred wiring harness
 

I'm only going by your avatar for what kind of harness you are shopping for, so I just wanted to remind you and let you know that the Suburban dash harness is different than the pick ups (and more expensive).
There is a large harness that comes off the fuse block to feed the rear half of the Suburban. At the time of my purchase (few years back) M&H was the only company making a Suburban dash harness, and rear harness that runs the length of the Suburban up the A pillar and along the roof.

Re: Preferred wiring harness
 

why would you have to cut the fire wall?

Re: Preferred wiring harness
 

I ended up buy a painless for $397 by having Summit price match and the shop was happy with the choice. Vectorit,I will let them know this info in the morning and see if we need to change things up. Since I am having a shop do all this work I am running out of cashola and didn't think I could handle more than $400 and the $1000 plus for the labor. I appreciate everyone's input. i may not be done yet. Wes I am PM'ing you for a price.

Re: Preferred wiring harness
 

Because where the fuse panel passes through the firewall it is larger than the stock hole. BB72CHEVKT, I am working on a quote for you. WES

Re: Preferred wiring harness
 

I just installed this in my '70 it was not too difficult and I don't know what I am doing...I can follow instructions though...so that helped. I passed inspection and everything :metal:

Re: Preferred wiring harness
 

all of the wire that needs to pass thru the fire wall will easily pass thru the stock hole. still cant see cuting the fire wall. even better would be to weld that hole shut and pass thru some where more out of sight.

Re: Preferred wiring harness
 

Didn't see it mentioned above but I really like the Ron Francis harnesses.

Re: Preferred wiring harness
 

Where the fuse panel passes through the firewall the fuse panel is too large. You have to enlarge that hole for the painless harness. I don't have any personal experience with Ron Francis wiring, but I have a customer with a 74 that paid a shop 1500.00 to install one. I told him he could have installed M&H he could have done himself. WES

Re: Preferred wiring harness
 

I just got my M+H from Wess last week and it was a perfect match and fit. :mm: :chevy:

Re: Preferred wiring harness
 

I used American auto wire classic update perfect fit

Re: Preferred wiring harness
 

When you intall these kits, do you begin by pulling all the old wiring out completely or do you run one of the new wires and then pull out the old wire one at a time?

Re: Preferred wiring harness
 

Pull all old stuff out

Re: Preferred wiring harness
 

I'm using a painless harness on both of mine. I've used the P/W on 2 other previous projects and other than a few plugs I had to overcome & fabricate...they went very smoothly and I had plenty of extra switched & unswitched circuits. 1 has been going strong for 15+ yrs.
