If you have an HEI tell AAW. they will eliminate that yellow wire. It's used to bypass the resistor wire for full batt voltage during cranking. If you have an HEI you don't need it, it will be full batt voltage all the time. AAW can eliminate the resistor wire. It's used for points ignition, not needed or wanted with HEI. BTW, you won't find a wire diagram with HEI, they didn't come out till 74-75.
TCS, it's not Delay, it's Relay. There is no Engine fuse, are you talking about the IGN spade terminal? It's not fused AFAIK
. It's where the HEI could be connected if you don't ask AAW for an HEI type harness. Ask AAW to eliminate the TCS wiring, the solenoid is probably gone and not worth replacing unless you're doing a 100 point restore.
All it did was cut off the vacuum advance while the engine was cold, supposedly helped it warm up faster. It was controlled by a pressure switch on the front right of the tranny if it was a TH 350. Eliminate if possible.
TCS reversing relay? not familiar with this, sure it wasn't part of the reverse lights?
5. Hi-blo relay, supplies direct battery current to blower motor when A/C is fan is on Hi. On the cars I've worked the big wire comes from the junction block, buss bar on the horn relay, runs down the left fenderwell, across the firewall in the plastic wire gutter. the fuse is inline at the passenger side of the wire gutter. goes to the Hi-Blo relay which is controlled by the fan switch in the dash. From the relay it goes to the fan located in the right side of the firewall behind the inner fender. Sounds like it's possible somebody tried to eliminate/bypass the long wire from the horn relay by attaching to the battery cable post on the starter? Be careful here, there's big purple wire from the ignition switch to the inside small post on the starter, that's what makes the starter start.
That yellow wire running from the starter to the coil would have been attached to the outside small post on the starter.
Dk Grn/Brn, what color are the wires to the wiper motor? Are they in place? I can't remember what color they're supposed to be.
If the car is not already changed over to to the 10SI type alternator with internal regulator this would be a good time to do it. AAW can modify the harness to eliminate the the old style external voltage regulator mounted on the back side of the core support near the horn relay. The ALT idiot light on the dash will still work right.
I'd get the engine and front lights harnesses from AAW with the mods mentioned. For some reason IIRC the long wire from the horn relay to the Hi blo relay is separate. Ask for it, the old fuse holder is probably melted anyway. Common problem on these cars.
Got all that clear as mud? Good.
