Late model Alfetta GTV speedo wiring question

Post by buzzed »

I have an Alfetta Veglia GTV speedo (electronic) which I wish to connect to my Dakota digital signal interceptor to take the signal from an Alfa 75 sender (3 wire). I have seen the other threads on how to sire and thats all straight forward. My question is this:

I have an Alfetta GT, I've removed the speedo (mechanical) and wish to wire in the gtv elec speedo. What pins go to what? I have 6 pins, 3 are obviously wires for high beam, dash light and indicator (thats fine). Then there are the ones that on the back of the gauge have a yellow, red and black wire going to (i assume) the elec speedo unit. Which one is the signal wire? I guess yellow, with red being +12v and black being earth.

Cheers!

Mike
