Hi,
Its been awhile since I posted, but my Wagon has been sitting blissfully in the pole barn.
I can't get it to start since removing the ABS Pump. I'm sure i need a ReFlash or something else to trick the ECM into thinking there's a Pump attached. Looking at the Manuals for the ABS, there may be several pinouts in the Large connector that could solve this.

Any Ideas?9099A7C6-23E6-4DFD-990C-1F0BF970F894_1_105_c.jpegE6A254B8-E592-42E3-8B5A-CB3B6A99C6D6_1_105_c.jpeg
