If so- then that wire is used for "kickdown", or "passing gear".
I thought the 350C's were long gone by then, and the TH-700R4's were in full production. The 700 started showing up in '82 didn't it?
T-350C was used for many years past 1985. I had a 1986 with 350C trans... GM exported the t-350C in various RWD vehicles for several years after they were dropped in t he USA.
We have even seen model year 2000 1/2 ton Silverados with a 5.7 / 350CID cast iron engines with distributors in our shop... these were trucks built for the Mexico market.... in the USA these trucks were all LS engine power.
Although if this truck 1985 was a 1 ton , it may have a t-400 trans in it
