Title: engine wiring diagram
Post by: 77c15 on August 05, 2007, 06:20:50 pm

Does anyone have a fairly decent outline for the engine wiring harness? My truck's wiring has been through you know what over the past 30 years (with roughly 7 different engines ranging from the factory 350,  a leaky 307, and a 383 stroker tossed in just for kicks!) and most of the wires are missing the terminals. I am pretty sure I have the 3 alternator wires and the large starter wire figured out, but I have several smaller wires with no ends, and i'm trying to connect the HEI, the starter switch, and the coolant temp. sensor correctly without frying anything. Any help is GREATLY appreciated. The truck is a 74 (factory points was removed in favor of the HEI). Thanks!

Well wiring schematics aren't layed out by the area the terminal ends are in. They are layed out by components or systems. So you can look up the starting sytem, charging system, lighting etc that way. Let me know exactly what system you need and give me your email address and I can send them to you.

The funny thing is, I work part time at AutoZone and they won't let us print them off the PC. Thanks!
