Was thinking about starting on the wiring now that I've got the engine bay all cleaned up for the swap. Something came up though, as far as power distribution. What pin on the firewall connector for the fuse block is for the main power feed? Also, is the power supply with the key in the ON and START position still in-tact under the dash? I plan on running the battery cable right to the starter, a wire from the batt. terminal to the alternator, and then a feed wire from the + on the starter to the fuse block feed. Just don't know which pin it is

 

Anyone have a pinout of the fuse block ?

 

this brings back memories of when i went from v6 to v8 carb. it easy if you take your time!!! basicly all you need is the wire to the starter, alt., batt, temp, stuff, what i did was just started cutting wires but left a pig tale incase i needed to go back and replace the curcuit. i will try to get a pic of something . i actually had to do it again for a guy who was going to carb from tpi(he backed out thought on the whole project and gave me the 91 z) si i might have the harness you need ready to go.

 

I just need to know which pin on the firewall connector is the main feed to the fuse block. I've gotten rid of the entire harness and I"m running all Autometer gauges. I can figure it out, I was just hoping someone here has done it already.

 

Found my manual and figured it out. Thought I'd post here for those that search int he future. Connector C100 that passes through the firewall and pins A4 and G5 supply 12v. to the fuse panel. A4 is for ignition switched circuits and G5 is for constants hot circuits. Now the only wiring I have under the hood is for the MSD, fan and gauge senders
