OK, it's been a while since I updated; some progress has been made just not nearly as much as I would like. As I stated in a previous post my progress to frustration ratio has been very out of whack! I guess the first problem is that I was working with wiring and that always takes way longer than I expect. I had a few things to accomplish with the under hood wiring:
- Get rid of the resister wire that went to the coil and replace it with a wire capable of running HEI
- Add a tach wire into the harness
- Extend the alternator wires since the 366 has the alternator on the passenger side instead of the driver’s side
- Get rid of the extra wires that were for the externally regulated alternator and make it like it came with the internal
- Unwrap everything and look for any problems that need to be addressed
The under hood wiring is in two blocks - first up was the “motor” side of things: ignition, starter, temp gauge and backup light switch.
I grabbed the under hood harness that was on the 89, from it I stripped the plug and wires that went to the distributor.
Next I used colored zip ties to mark various things on the original harness: red is where the harness branches, green is where there were tie downs, white marked where the harness was connected to the “gutter” that runs across the firewall. (Note the blue masking tape where I marked the connections when I disconnected the harness from the old truck)
Then I unwrapped the old wires and separated out the ignition wires. I pulled the resistor wire from the connection that screws to the fuse block, cut the old wire loose and then soldered the big HEI supply wire and then rewrapped the harness. The other wires were all in good condition. I also had to extend the tach wire. Then I plugged it back in to the connector
To be continued...
