I was thinking of mounting the battery on the driver side and mount the computer under it.... I think the fuse box ends up on the driver side....

I got my pedal from them but I'm ignorant as to what a TAC is.
I may need to get one.

Thanks.
Jon at PSI recommended the E38 over the computer that came with the engine.

truckzilla · 02-29-2012, 01:20 PM

I sure will since you're just up the street in what we call Far North Texas! I hope to talk to them today and get the ball rolling.

I'm using there harness for dbw with the 4l80e I had #3 injector wire and the driver side coil pack wire pull out of the terminal so I called them up and they apologized for what happened if I remembered right I could of sent the harness off and had it checked and repaired but I already had installed so they sent me a packet of terminals and fixed them my self,

STOCKISH · 03-03-2012, 01:35 PM

Yes, thats all it is. You will still have the neutral safety switch on your steering column hooked up.

truckzilla · 03-05-2012, 11:48 AM

Hey Aaron, I had forgotten that you had said you were using a PSI Harness as well. I am probably years away from needing it, but I figured I better get it now while I still had a little money left from the IRS savings account.

mooseknuckles · 03-11-2012, 11:53 AM

the only thing that I have found that I dont like about the PSI harness is that the wire for the MAF isnt going to be long enough to work with my cold air intake......

flamingbig10 · 03-11-2012, 12:03 PM

Larry that's correct, John the MAF wires on my harness are the same way, I going to lengthen the harness, I'll just need to get the factory piece that mounts the air filter to MAF

mooseknuckles · 03-11-2012, 12:10 PM

I have a k&n and the maf mounts to the cone and its about 16" away from the throttle body....so I guess I'll do the same as you...or maybe there a pigtail to extend it?

52 Rat · 03-11-2012, 06:49 PM

Guys, Jon at PSI can make you an MAF extension or you can buy from someone else. Do a Google search for MAF extension and you will see vendors on ebay and other outlets.

truckzilla · 03-12-2012, 10:03 AM

Thanks Rat. If you guys find a good price on one, please let the rest of us know. I'm guessing I'll probably be needing one as well. I checked with PSI's online store and while they don't have one listed, I'd have to agree in that Jon could probably whip one up.

Yes, you will need to contact Jon (PSI) directly for this.

truckzilla · 03-12-2012, 10:15 AM

I'll have to remember to ask him about that when I call Jon back with the details to get a E38 ECM ordered from him.

farmtrucks · 03-12-2012, 01:20 PM

Very pleased with my PSI harness - I've installed 2 of these without any problem - I lengthened the maf wires

KMC3420 · 10-31-2014, 01:49 PM

For those who got the PSI harness, did you get the AC recognition for $15? Jon at PSI said it adjusts the idle when the AC is engaged.

kevmac · 11-01-2014, 11:14 AM

I got the a/c lead, ended up not using it. I have vintage air and wasn't sure which wire to connect. Nice harness

KMC3420 · 11-01-2014, 11:27 AM

Thanks for the info. I passed on the wire. Jon said I would most likely not need it. I plan on going after market ac as well.
