ty/sy ecm pinouts anyone?

I found several on here but, nothing complete does any one have one? I have the ecm, 2bar map and when I do the swap in the spring I will be using a S/C with a boost bypass valve I bought from work. (way cheaper than what powerdyne and vortech want) my plan is to use ecm to control the boost untill I hit a decided MPH. the ecm is already made to work like that but, I need the wiring to do it

I'm confused as to what you're trying to get. Bort's page has all the neccesary repinning to get to the 749 from the 730. Are you trying to find the pinout to get from the 165 to the 730?

they don't show the wiring for the boost control.

bassically it will keep it from making boost untill I am really moving and can use the added power

John Millican, thanks thats just what I need.
