Attachment 185487

Any help?

What is it you are trying to wire in

Remote start I just need this relay
And nutual/park ground and I think I'm done

Tach wire too

I never used the tach wire in mine. this should help. Just select the make on the side and find your truck.

What about the mutual/park ground ?
There's one wire that goes to key cylinder input where's that at?

Go here and find the config you need for auto start.
