My 1971 GMC has two relays (tcs and emission) on the engine side of firewall just above and to the right of the fuse panel. The Blazer doesn't have these relays. Does anyone know, is this a Blazer thing or a 1972 thing. I want to find a underhood harness but don't know if the harness would have to come out of a Blazer, or could it be out of a 1972 C or K truck also.

Here is a picture of the TCS relays.
I think all 71 gmc and chevy vehicles with the 350 th had them even 6 cylinders. not certain however.
If you go to the search bar by your private messages and type in TCS then tick the 67-72 circle and click google you''ll get a lot of info in the tcs stuff.
