i have a 2005 f150 XL with a 4.6L. I bought a sunpro tach and im not to sure where to splice in the green wire. ive seen other posts for older trucks using pin 48 on the ecm and others using an injector wire but i dont really want to try and end up frying my ecm. any help would be great.

It is meant to hook up to a wire coming off your distributor...

You may be SOL. Hopefully someone else can be of more help.

its the pink and white wire from the pcm. do not touch the injector assy' or anything from the coils, if u cant find the wire in the engine bay take the dash apart
