lt1 plug.year. 1995. plug 220 cavity G Dk Green/White Vehicle speed signal.
where does this go in a 1990 camaro rs tbi?

 

I can't remember if the 90 camaro still had mechanical speedo or not. C220-G dark green/white wire goes directly to the speedo input wire on the electronic speedos. You may have to swap gauges if yours wasn't driven by an electronic vss.

 

90+ where electronic. but what im looking for is speedo input wire on the electronic speedo for the 90 camaro.

 

i know my 86 t/a the wire was located under the passenger side lower dash. It had a yellow vss box. One of the wires coming off that box was the input for the speedo. I'm thinking it was the tan wire. I'll post a pic I found on my computer.
