Perhaps a search would help! the search should be your best friend. unless you wanna get flammed for not unsin it..

 

wire one ground and a hot wire together, and run that to a ground source.
wire the other hot wire to a powered source (only on when car is on)
then wire the signal wire to where its supposed to be.

 

what ecu do u have? obd1?

 

yeah i have an odb1 ecu p75

 

the green is a ground, the white is signal, and the blacks can be switched... one is 12volt, and the other is heater control, They need to be wired correctly to work
