I bought a used current performance fuse block and trying to figure out a the starter and AC relays coming off of it and their purpose.

Here's what I have, I am re-wring my stock 2004 5.3 harness (already modified) with this fuse block and not sure if I even need those wires. I have a Vintage air AC system installed on my 71 Camaro too.

AC relay (why would I need this?)

green wire - (AC compressor -going to ac relay)

Light blue (ac request - going to AC relay)

Starter Relay (why would I use this?)

Yellow / black - Cranking Signal (going to starter relay)

Thick purple - going to starter relay (I'm assuming this goes to the starter lug)

I belive that fuse box is very similar to the one i have from bp automotive

Yellow/black should be crank/signal wire. Probably a 18ga wire, should go to a 12v switched wire from your cars dash harness.

You may have a pink/blk wire too, this should have 12v. Constant

Yes "thick" 10 or 12ga wire should goto starter

A/c stuff not sure on as I deleted it all.

This off top of my head, someone please correct if wrong.

You will only need the AC relay if you want the PCM to control the compressor.What are you using for a neutral safety switch?That will determine if you need that relay or not,if you are using the stock Camaro switch and starter wiring you simply can use it as it was.

I'm using the stock style starter wiring that came on my AAW update harness. My ignition switch is stock too

ok, I'll go ahead and remove the AC feature. Doesn't look like I'll need it.

Thanks both of you

edit: Doing some research and it looks like I can install a vintage air trinary switch and use the AC request feature to power on my fans when the ac is turned on
