Swapped my ugly 87 digi-dash with 86 dash and now I'm pulling an ECU code 33. It's a vehicle speed sensor. I don't have all the wires hooked up yet. Any one have any suggestions? (Subie81)

i beleave the VSS wire is yellow. and you will need it. if your 86 dash was out of an injected car it should have it. if it is out of a carb. car. you may have a problem.

Yeah. That was one of those unresolved questions. That wire is clearly marked on the 86 FSM diagram as wire 4, but, though it is labeled as speed pulse on the 87 diagram , it does not show what number socket the the wire feeds. Do you know which socket that is? If not, this should be easy enough to track down.

 

PS. Again, I must thank Subie81 for providing the FSM diagrtam pics. Absolutely could not have gotten this far with out those.

Looking back at my notes I have analog #4 (speed pulse out) connected to Digi #13 (speed pulse). The analog dash came out of an 88 RX so I think superdave may have a valid point. You might have to run your own wire? from the speed pulser in the dash to the computer.

My analogue dash has that connection. When I'm done with everything I am planning to post a list of conversion tips. This will be one of them.
