Anyone done this? Kind of confused between the standard wiring diagram and the T3 directions. Would really like to use the stock ignition switch for looks purposes. Any help would be much appreciated.

So that's the Harness from West Coast Bronco's? My understanding you cant use the stock ignition switch. But I do hope its not too complicated, I intend to use it myself.

Please don't tell me that. I don't see how that cheesy ignition switch attaches to the same spot on the dash. Looks like ass.

Are the T3 wires labelled? You should be able to use the stock switch and connector. Should have all the same wire functions.

Yeah, but what's really confusing me is the directions for the T3 harness, compared to the stock wiring diagram. These directions seem to over simplify it. May need to enlist some local help before I screw this up completely. This thing came with a pile of crimp on connectors. From what I'm reading, I should toss them and start soldering everything together and use heat shrink to cover. Sound correct?

That,s what I would do.

I didn't use the keyswitch that came with the kit because i wanted to use the stock one. I ended up cutting the wires about 6 inches from the keyswitch plug to be able to reuse it. The kit did not have a wire to go to the voltage regulator, so i ran a red wire from the grn/red on the switch to the regulator. The red wire(B+) in the kit from the fuse panel went to the yellow on the keyswitch. the yellow accessory wire in the kit went to the grn/blk on the keystich. The purple in the kit went to the red/blue on the keyswitch to the start terminal on the starter solenoid. And i am using a pertronix ignitor so the red ign wire in the kit went straight to the positive on the ignition coil.

I used the schematic on this website http://seabiscuit68.tripod.com/ along with the instructions that came with the kit.

Also i did not solder the terminals because i was not 100% confident in my soldering skills because its been a while. So I used non-insulated butt-connectors and adhesive lined heat shrink.

Hopefully this helps you out. Overall the kit wasn't too bad and thankfully nothing went up in smoke when i started it the first time. The only thing i can't figure out is when i have the emergency flashers on they work like normal, but when i step on the brakes they light up solid.

Yea no problem. Let me know if you need any help. Also one thing I forgot to mention. Off of the I terminal on the starter solenoid I ran another wire to join in with the red ignition wire from the key switch to the coil. So if you look on the 68-71 ignition drawing it is wire 262 a tan or brown colored wire

I am was not sure if it was needed or not because I am not using a resistor wire or ballast resistor. Because I am using a pertronix igniter and it needs full 12 volts they said.

Have a good New Years!
