Ok Phil I did not see your post until today. GC

Does anyone have a pin-out of the Tech 1 main cable?

I'm attempting to piece together a Tech 1. I have a Tech1 and the cartridges and adapters I need for my application but I don't have the main diag and power cable.

From the pictures I can find, in a cursory Google search, and looking at the hardware I have right now.
It looks like the cable needs to be a Female 15 pin two row D-SUB to a Female 14 pin Amphenol 57 series "Centronics" connector with a cigarette lighter plug on the end of a power cable and binding screws on the Amphenol plug end...

The Tech 1A would have a Male 26pin three row D-Sub to 14 pin Amphenol 57 and I can find those cables. Or I could last time I looked. They're in tough shape but I can find em... I'd buy one and just ring it out but I don't have a Tech 1A.

The most popular cable for a Tech1 is a TA01139B - that is the the GM ALDL and a cigar lighter input. There are others but that is the more popular. I have a couple Tech1 (not 1A) here. There was a Techline cable when first released to GM that had the correct pinning, the cigar lighter supply and also an 'out' female connection. The Techline I believe is a TA00011A. I have both styles.

Do you know that the Tech1 is functional? If you were closer I'd lend one for a trial. New Hampshire doesn't work.

Unfortunately I'm not positive that it works. I can't easily power it up without the DLC cable. If it doesn't power up I can probably fix it as long as the fault isn't an obsolete part. Just time on the bench.

I take it the 14 pin Amphenol 57 ended cables were a Tech 1A only item.

Soooo. If I'm not incorrect.
The TA01139B is a two row Female 15 pin D-Sub to a molded 12 pin Male Metripak 280 ALDL plug with power in via a cigarette lighter pigtail on the back of the molded ALDL plug.
The TA00011A is the same as the above except power in is a jack?? and it also has power out for the adapters that need it.

The Tech 2 DLC cable has a power input at the diagnostic connector end. I own a complete Tech 2 that came with a 12 pin male Metripak 280 ALDL connector.
I bought the Tech 1 to use on my 1988 R2500.

If I had the pinout of the TA00011A cable, including the power in and out, I could build a converter to mate the 15 pin two row D-Sub on the Tech 1 with the 26 pin triple row D-Sub Tech 2 cable that I already use with my Tech 2... that's likely the route I would take.
The adapter would essentially be slightly more complicated than a gender changer.

I'd share my success or failure and details on the adapter pinout with this group for the trouble.
Once it's proven to work on the Tech 1 making an adapter for the Tech 1A would be a cakewalk.
