SY POWERED SGT
New member
Finally go around to putting the SY/TY engine in my SGT. All of the wiring plugged right in but when I powered the truck up, a few things didn’t work.
Check engine light
No power to the ECM
No power to the fuel pump but the fuel gauge does work
No power to the left headlamp or signal lamp
Everything else works
The dash harness is the original for the SGT but the engine harness I think came from a Typhoon (due to the white overspray on the shielding) but I am not sure what year. There is no plug for the washer pump on the engine harness like the original. I was able to find a home for all of the plugs. I never got the ABS or the harness from the donor vehicle.
I know that the SGT dash harness does not have the 932 wire for the boost gauge, 904 for the low coolant and the 852 for ABS light and I did have to move the location of the 419 wire for the check engine light as the arrangement on the SGT cluster is a little different.
On the C101 plug near the ECU, not all of the wire colors match on either side of the plug. Not sure if this is where I should start? Any help would be appreciated.
