1966 427 TI Wiring Harness
I am very confused as to why my 1966 big block has a long unused pink coil/resistor wire that is just coiled and taped back to the harness just above the wiper motor. All other cars I look at do not seem to have this wire. What am I missing???

John,
The TI cars use the pink wire from ignition switch to power the TI harness. The wire from the ballast resistor to the coil is not used, just the wire from the starter solenoid to the TI harness distributor plug pigtail.
Do some reading in the archives, it's better described there and maybe a picture for you to check out.

This is the pink wire that I am confused as to where it goes??Last edited by John M.; February 16, 2011, 04:29 PM.Comment

John,
That two wire connection is a wire from starter solenoid to coil + and ballast resistor to coil +.
With TI, only the wire from the starter solenoid is used and that goes to a pig tail at the TI distributor plug. This provides 12V when cranking the starter, the other wire is either cut or taped on both ends..

Dave, If I understand you. I should cut these two pink wires and just tape them to the harness. They have not been used, just coiled and taped to the harness above the wiper motor. What confuses me is that they have a connector crimped on the end that appears like it should be connected to a screw such as the coil etc...Comment

John --- I'd like to give an opinion, but I need more information. Looking at your photo, I see an aluminum intake (nice overspray
) which points to L72, with K66 mandatory. Do you know if your engine harness is a reproduction ? Reason I ask is the factory engine harness was the same for all engines (TI or not; C60 was 2nd version). The mods were then performed to accomodate the amplifier harness on L72, or on L36 or L79 with K66.
What's strange (as Tim has pointed out) is that there are two wires to the same side-terminal connection (that would normally go on the coil +ve on a non-TI car). So one of these [the pink wire that goes to the R terminal of the starter solenoid] is not helping the starting operation with max voltage to coil (when key held to start position).
Your car might still start; even a contact points ignition set-up doesn't really need that full voltage from the solenoid (but it certainly helps). Have you noticed your car has trouble firing when cold ?Last edited by Wayne M.; February 20, 2011, 06:41 PM.Comment

Hi Wayne, Yes my car starts very hard when cold!! When warm no problem!! I would assume the harness is not original. The car had a complete body off restoration in the early '90s and I have been told that they replaced the harness in the engine compartment. The strange thing is these two pink wires have a crimped connector on the end, just like you would put to the coil etc... it also appears that this connector has been hooked to something in the past. When I purchased the car this wire was neatly coiled up and just taped to the harness above the wiper motor. I have noticed other TI cars not having this wire showing. What do you suggest I do!! I really appreciate your imput!!Comment

John,
That connector with the two pink wires comes apart and one of the wires, (the one from the starter solenoid) goes to a pigtail on the TI harness distributor plug. This will give 12V when cranking the starter.
The other wire either gets cut flush or just taped, I am not sure which one.Comment
