Do the 4 wires going to the injectors need to be in a certain order?

Asked by Nov 12, 2014 at 03:49 AM about the 1994 Chevrolet C/K 1500 Silverado Extended Cab LB 4WD

Question type: Maintenance & Repair

My original throttle body needed replacing and I needed more power to tow a trailer.  I
bought a Holley 670 cfm replacement, which was an OEM replacement and Ca. legal.  
During installation I may have gotten the wires switched. After I replaced the throttle body
I'm running rich.  Could this be the cause.  If so, what order from left to right should they
be in.

Yes, the wiring needs to be in the correct position. Sorry, I don't have a diagram. Maybe someone else can chime in.
