How is everyone wiring thier trucks after the swap....Mine is a 12 circut Painless Wiring Harness....And let me tell you, It dont get no easier than that. I had all kinds of hell with the stock FI harness shorting things out so that was the best thing.

I used the stock wiring. Well not all of it, 60% of it went in the trash.

Ditched all the wiring for the computer. I reused the wiring for the alternator, and the starter. Then just 1 hot wire to the HEI.

i found the easiest way to do it when switching to a carb\'d engine is to go to a wrecking yard and get a wiring harness from a 86 or older s-10 it should plug right into your fuse block and only has the wires you need... most wrecking yards will be glad to trade you your f.i. wiring harness for a carb\'d one...

Which wire is used for the HEI distributor when converting from a 4 banger to a v8 monster? Any help is much appreciated. http://www.s10v8.com/images/smilies/icon_confused.gif

99.99% stock just movedthe clutch switch to the shifter so it will only start in park but not neutral and added 1 wire to coil + from starter to make start better
