86T digital dash, auto Climate control conversion

[edsz31]

Hello I have a 86t, I have a 87t doner, want to swap the transmission 5 speed, analog dash, auto climate control. Only I'm not sure about how to convert the speedo, it does not have a speedo cable, my 86 has a speedo cable to the speedo sensor. I have not looked at my engine harness to see is the 87t transmission harness will just plug in to mine. Any idea's ?

Unscrew the little electronic unit from the 87T transmission and hook up your cable from the 86T. The Cable on your car runs to a electronic sender by the battery, while the sender on 87-89 is screwed right on the transmission. I don't at all know if the signals they send out are the same.

My 87 with the digital package had the sending unit by the battery.
My 88 does have it on the trans though. A much better set up in my opinion.

Maby I just need to swap the dash harness, and see if the transmission harness will plug in. I may just get a 84-86 analog dash and try to find a white dash face.
