Calling BOB BAILEY

[turbot990]

Bob what i have is a casper,s 87 buick stand alone engine harness we are trying to hook up your 2 step to this wiring harness but we don,t know were b-4 is located on this after market harness,the harness is a b2b fast classic direct plug in which we now have a casper,s plug and play adapter to a XFI so my question to you is what wire off of casper,s engine harness will your 2 step hook to as of b-4 thank you.

you can find B4 at the ign module , pin A (last wire by the firewall)

youll also need to wire the fuse plug section of the two step into the ignition module 12v supply by splicing the power to the ignition module at pin P and pin M
one of the fuse holder goes to power supply side of P and M wires , other side of fuse holder goes to ignition module wires at P and M (the last wire near rad side of connector and the third from the end )

What about catching it at A14 just before the xfi box. Tan wire with a black stripe......

 

[turbot990]

Ok off of caspers plug and play adapter a14 is the same as b4 on the buicks factory wiring harness correct

if you look at your ccom wp xfi program , help/ index/ table of contents 3.0... is a pinout

but yes A14 at XFi, B4 at ecm, or pin A at ign module are the same ,, the EST
