The last few days I've been working on getting all the wiring finished up. First thing was to get and install a new positive battery cable, as the one I had lacked about 6 inched of being long to get to the battery terminal. I thought I had some 0 gauge cable, but I didn't, so I picked one up at the local battery shop. The terminal on the starter isn't easy to get to with the headers on, cold fingers didn't help, but I finally got it on. I cleaned off a boss on the front of the block so it would make a good connection, and installed the ground cable. It's a little long, so I might shorten it later.
I got all the lights working after a couple of glitches, i.e. no backup lights, and wrong color wires on the front park.turn lights.
The backup lights sort of stumped me for a while, I had power to the backup switch, power back up to the transmission harness plug that connects to the bulkhead connector, but no power to the wire coming out of that connector. That connector is a female, and using a paper clip, there was power there, but when it was connected no power came out the other side. Pulled the connector apart and found I hadn't gotten the pin pushed in all the way and wasn't contacting the male pin. I got it seated correctly, plugged back together and I had backup lights.
The turn signals have a blue and a black wire coming out to connect to the harness, blue for turn, black for parking lights. The harness was wired opposite to that, black for turn and blue for park light. Hmmmm. So, I swapped the wires in the connectors on the lights and connected them to give them a test. Well, it appears they are wired incorrectly, so black goes to blue, and blue goes to black. They are even swapped according to the factory wiring diagram.
Next, I ran the wire for the water temp sender, tying it to the main harness on the firewall and then forward past the distributor, up to the sender, installed an eye terminal and attached it to the sender. I checked it by shorting it to ground, and that made the gauge read full scale hot, so it works. Did the same with the oil pressure sender, and it works too.
I cut to length, installed braid on and put the connector on the horn wire. I had tested the horn and it works, but someone had bent the mounting bracket, I have no idea why, but I heated it up and got it bent back close to how it should be shaped. Popped it in the blasting cabinet and got rid of the burned paint, then gave the whole unit a fresh coat of black paint. Looks like new now.
So, I think the only wiring to be addressed is to secure the harness that runs across the radiator support with some loom clamps and screws.
I need to blast and repaint the top radiator mount as it looks pretty bad, then I can get the radiator installed, heater and radiator hoses installed and fill it with coolant. I also need to get 5 or 10 gallons of gas and put it in the tank, and it should be ready to start up.
Getting closer!
