Jeep TJ 318, 360, 5.2, 5.9 swap PCM W/VTSS bypass!
This is for those who have swapped in a 318 or 360 from a ZJ with VTSS enabled. If you can only get your swap to run for only two seconds, this is the likely cause.
First, remove the BCM from the drivers side, under the dash. Should only require a Phillips as far as I remember. Make sure to leave a few inches of wire on all three connectors.
The BCM consists of connectors C240, C241, and C383. From C383, you will ground the black and orange wire BK/OR (ground) and the purple and yellow wire VT/YL (VTSS SENSE). From C240 and C241 you will ground the black and orange BK/OR wire and the black BK wire. The purple VT wire in C240 (the one with the thick black ground wire) goes to a fused 20A source. I made my own, but you can use the cigarette lighter wire if you are stuck. That leaves the purple VT and the white and black WT/BK wires in C241. Those are your CCD + and - respectively and will splice into the same color wires coming from the gray PCM plug. That's it! You have bypassed the VTSS!
