Power Supply LT1 Conversion Question.

[sshockr]

So I'm coming to the end of my LT1 conversion. I have a quick question though.

I built the LT1 harness to be completely standalone. Now the LT1 side has a central power post. My understanding of the 63 harness leads me to believe that if I go from the aux post on the modern side to the Horn Relay on the old side of things, all the original parts / namely the lights will have power as required.



This is my new under hood electrical center. The small block off to the right is the positive block. I figure I need to run from there to the Horn Relay?

The 4 prong connector is for the electric fans.

Yep,

The old truck is powered off the connection at the horn relay (except for the starter of course).

Yeah, my starter circuit is all new from the bed mounted battery and ford remote solenoid to the 'vette starter in the front.

Guess I was just looking to confirm where I'm running wire to. I suppose in the future I'll probably build a custom harness for the truck side of things too. Figure remote relays for headlights and all that but for now I just need it to run.

Where did you get the "positive block"? It looks similair to the one that Mad Electrical sells

Jegs. It even has a nice little cover that doesn't fit once you put 3, 4ga wires on there.

So if I run 12v from my block to the horn relay what do I do with the old external regulator? Do i ignore it because the regulator wires aren't connected anyway?

Thats what I would do unless a circuit is junctioned across one of the terminals. If not, I would then proceed to unbolt it and throw it away.
