starter wiring???

[dman1982]

so kinda a odd question but what wires dont i need anymore?do i need all those wires going from the firewall for the starter since I'm doing my swap? does anyone have a wiring diagram or pics of what i don't need anymore? I'm hoping to put my harness in tomorrow and don't want a bunch of access wiring in there i don't need....84 k10 5.3 swap

Not sure how it is on an 83, but on my 66 there was a separate passenger side firewall connector for the starter and a couple sensors (originally a 292 in there) and maybe a coil wire. I cut all that out except for the starter wire. I ran that terminal to a relay then to the purple starter wire in the 5.3 harness. Make sure to plug empty connector holes with RTV and be generous with the dielectric grease. Fingers crossed I've only had some very minor gremlins. Good grounds to body, engine and frame are the key to makin these things solid.

me and my buddy put my harness in today, he was telling me that gm left most of their wires the same as far as 12 volt +, constant power, and etc, and the colors stayed the same...is what i was really asking was how much can i cut out from the old harness? like the "jumper for the solenoid and etc

man i dunno, I just copied what the lt1swap.com dude has on his site.

The starter only needs the battery cable and the crank signal wire. My truck had only one more wire - for the ballast resistor - and the PO had already eliminated that with a HEI conversion. So I just took the wires I had and put them back on the LS starter.

When I get home I'm gonna take a pic of what I think your talking about

[dman1982]

This is what I was talking about, do I need it?

[mooseknuckles]

you can delete that if you don't want it...I forget exactly how I wired mine after I removed it, but it's not hard to do...

[dman1982]

What's it for?

[littlevictories]

looks like a power distribution block to me.

[dman1982]

It went over to the a/c...not sure what it was for...any ideas?

[mooseknuckles]

distribution block...if you need 12v power, you can tie into it there, not sure why the a/c is wired to it?, but I don't have a/c so can't say for sure.
