abs electrical connection question.

[RobMatthews]

Im installing a new wiring loom in another fd i have aquired.

Question is on the passenger side there is a wire coming up from the passenger side wheel and resting under the abs unit, but i cant see a plug on the new loom for it and the old loom is in bits(-from the previous owner) can anyone please confirm where its supposed to plug into?my track fd has all that removed so i cant compare:confused:
