Is this all for the TCS Harness?

[sick472]

I have a small harness from my 72 and I am thinking it can be deleted. It went through the firewall where I am pointing at. The relay looks like it mounted above the horn relay by the steering column under the dash and should be Trans Control Spark Relay. I will not be putting TCS back in.

Is this whole mess for the TSC?

Or, are there wires in there which I may need?

That appears to be all of it. If all your equipment works, you didn't lobotomize it too much. Did you also remove the solenoid from the passenger's side of the intake manifold? You don't have to take the pressure switch off the trans unless it is leaking.

Looks like it to me. I used the 10 gauge pink wire for my HEI installations on both my 72's. There was an idle solenoid and a vacuum switch located on the intake. Getting rid of all that really cleaned up the motor. I don't recall having those holes in the firewall though...

Yup, that is definitely it. As Ironangel said, you can use the pink power wire for something else.

Thanks for the fast repies!

This resurrection from the dead now has a Pontiac 400 and TH400 transmission. So, no original under the hood equipment left and "lobotomize" is not a strong enough word. I am in the process of bringing all the electrical equipment back online and all I have proven out is the lighting thus far. I'm working on the custom gage cluster and engine wiring now. Heater controls are in the waiting.

I will be using the old resistor wire circuit (with the actual resistor wire replaces with 12 ga wire) for feeding the HEI. Looks like I will be plugging a hole in the fire wall...very nice.

I think I will ditch the whole harness, meaning put it in a box just in case somebody can use it someday.

Oh, and I found this today...I think this is for the 70 TSC wiring, but 71 and 72 should be the same. It's starting to make some sense.
