Hi guys.

Question, proposal may sound stupid. Need a basic schematic of engine wiring. E.g. wiring from bulkhead connector to starter, battery, distributor, alternator and so on. No ECM, no sensor... Just the basic.

350 carburated engine (1st gen engine with HEI distr). Wiring harness from a 1986 Camaro. Using the fuse block and bulkhead connector. 1986 Camaro dash with wiring in a 1983 Firebird. Harness is in bad shape, all cut up.

Wires I'm using:

A4 - power distribution, ignition switch
G4 - Power distribution, light switch, fuse block



Thanks in advance

 

You should be using everything in those two tables.

 

You need 4 basic connectors from the original harness

C100 which you have listed
C207 near the old ECM
C221 near the old ECM
Hvac connectors on the hvac box

C100 has mostly power and gauges
C207 has cluster ground, maybe more can't remember
C221 has the fan relay fuse
Hvac powers the blower fan and Ac

Do a search for the additional info thread for individual pinouts, relay diagrams etc
