I am in the beginning stages of fabricating a new harness from the bulkhead connector to the engine for my 1985 El Camino. I thought that I would document the process here. My 1985 EC has the following equipment attributes (which need to be considered for this wiring project:
1. factory gauges for volts, coolant temperature and oil pressure;
2. I want to also run idiot lights for coolant temperature and oil pressure (my recollection is that the gauges had no idiot light backups);
3. I am running a Mountain Man built Quadrajet carburetor;
4. I will be running the electric choke and idle solenoid (which kicks in when A/C is turned-on);
5. The original SI alternator has been replaced with a CS alternator. I purchased a SI-to-CS alternator adapter (however, I will likely cut the one end off and just solder into the new harness);
6. I will be retaining the original oil-pressure switch in the choke circuit;
7. I have installed a ford solenoid adjacent to the battery (on the passenger side);
8. Fusible links will be run from the ford solenoid (mentioned above in point #7);
9. I will be running A/C on my EC;
10. I have installed a power distribution junction block on the firewall; and
11. I intend to run relays for the idle stop solenoid and the choke (this way the voltage can be routed through the relay from the power distribution junction block).
