.040-.045..no need to go anymore with the older style plugs.

Thank You for the info, however I have an HEI distributor with the 12vdc terminal and the tach terminal. All the early TCS and Auto trans are gone and wiring is different. The Dark Blue from the temp sending unit now goes to the 12vdc terminal on the distributor. What used to work is not working now, I loose the voltage to the distributor causing no spark. Having no updated wiring diagram from the new work is making me go wire to wire to track where it loses voltage. I'm sure you would not have a problem with your background in racing, but this is my first muscle car wiring and restore to a drive. Learning though is frustrating but challenging and I take a challenge seriously. I think from this point on I will take pictures and look at the diagrams of the '70 originals and compare and change the diagrams to what is now on the car. OK enough for one night, I don't want to bore anyone more than I have. Thanks again jciwolf

I don't think it's boring.

Trying to understand the situation.
With the HEI addition, I was wondering why the interest in getting the TCS working.

The blue wire should not be used to power anything I would say.
(plus it originally had no connection to making the distributor to work)

It's best to think of the wiring as sections.
If you need to work on the distributor, just concentrate on that section.
(which the TCS is not part of)

Basically the distributor (in your case) needs a switched 12 volts to make it work.
If it gets 12 volts with key on, then it should work.
Doesn't really matter where that 12 volts comes from but usually want it to be a dedicated wire.

As to the emission circuit, I'd just tape the ends up.
(since you don't have all the components)

Tell us what doesn't work and we could figure it out.

I haven't looked at your diagram link but I will after this note. Today I checked three wiring diagrams, all with slightly different things and wiring. They did all point to the pink and black/wire from the ignition switch. I ran a new wire as the original is gone due to updates, to the distributor 12 vdc terminal, which only gives voltage with the ignition on. I put the car in acc and the wire had 12 volts, when I put the wire back on the distributor and tried to start it all voltage disappeared! If I wait a minute or two, now in shock, the voltage comes back, At this stage it was 7pm my time and time to roll it in. Saturday I will check for shorts, not sure if my distributor is a problem or my voltage regulator? Best way I know how is to disconnect the battery first and check for grounded wiring, by testing the + side to ground and then + to -. I will find it, just hoping it isn't something worth big $$$$$. Thank you again for your help, this is becoming an exciting and frustrating project. Now onto your diagrams jciwolf
