Which wire is it on the idle motor that some people neglect to hook up?
Is the wire for the fast idle? and does it just need 12v?
When I did my harness all I remember is hooking up power to a black/yellow.
As long as you wired up your sr rigth or to the instructions on heavythrottle your fast idle sould work. I did my friends like that and he worked. At first it didn’t work due to the starter signal fuse was blown and the computer uses it for cold start and for the fast idle to keep it from stalling. If the fuse is there and not blown check power to it when cranking.
