Sorry my bad english, I do have a on/off switch to supply 12v to TAC C1 pin 14 so that should be ok. Tonight I will ring all cables to se that everything are at the right position. I will come back with a uppdate.

I'm sure your English is way better than my Swedish!

Here's a write up on how to wire the relays to the DD HND3 cruise lever. http://67-72chevytrucks.com/vboard/s...d.php?t=398006

This is the style of lever I have.

You are probably right, even if swedish is not that hard to learn.
I will go on a business trip to Philladelphi in the end of july so I will order the CC lever to my hotel room.

I have adjusted the switch in and out, same result. Just to make sure, the TCC wants to see 0 voltage when the cruise is engaged? And 12 when the brakes are applied? If this is so can I simply unplug the TCC wire, or temporarily ground it to verify?

I find my problem, the cable 1320 TAC C1 Pin 6 was hot when brakes was not applied .... so I hade wired the reversed way !

The light blue wire, pin 6 on the TAC module needs to have 12v when the brakes are applied. The TCC is just the opposite, I don't think unhooking the TCC is going to help.
Good deal!
