I believe I have an 88 tranny. It has the speedo sensor rotor that has a purple wire and a yellow wire. Can anyone tell me what the function of each of these wires are? I am trying to wire a VDO speedo and have run up against a wall...
Assuming you have a fuel injected engine . And, you have a VDO programmable speedo, The vdo signal should feed off either wire. Ppl. is VSS low,it varies from.60 to 12vdc as wheels turn. Yell. is Vss High " " " " Hope this helps.
