I Have A 87 Gxl That I Have Done A T2 Swap To And I Found Out That I Am Using An S5 Harness On The S4 Motor Is This Goin To Give Me Problems And Is Any One Running Their T2 With The Bac Valve Blocked Off I Have All Emmisions Removed And Rats Nest Stock Comp Still Running 550's So Pretty Much A Stock T2 Just All The Crap Removed So If You Can Help Me Out I Would Appreciate It

 

thats hard as hell to read man, why all the caps??

Yes. There will be differences between the harnesses.

There are plenty of people who remobve the BAC valve but why would you want to do this? It really helps your idle so unless you know you want to remove it for a specific reason you might want to keep that.

I'm removing some of the emissions related things on my '87 TII such as the Air pump and AVC, EGR valve and sub zero start assist as well as most of the rats nest.

However, I will be keeping the BAC valve, the air supply valve and air bypass valve, the thermowax unit, the metering oil pump and some choice solenoids. These are often removed along with the rest though they're not really related to emissions, more idle and oiling so I'll keep those so my car idles and I don't need premix.

Basically IMO you should keep the BAC Valve.

 

The keyboard offers a variety of keys, aside from the usual letters and numbers. For instance we have the "." key. This denotes the end of a thought, letting the reader gather his wits before setting about the next train of thought. Next we have the "," key. This is the comma, it is a wonderful device created to join two closely related thoughts together. It's a team effort! Finally we have the "Caps Lock" key, a key which you have hit once before, and never again. It is located under the "Tab" key and above the "Shift" key. Please press this key once more, and leave it from your thoughts for eternity.
