UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.
It is hard to say for sure from here what this plug is for but if it is on the engine it usually is required for a function on your engine to operate properly.You may have to swap out the wiring harness and computer and have a dealer reprogram your vehicle.This has to be done in some cases.
Let me know if you need anything else and feel free to rate my help here.
Unfortunately this is all of the info I have on this here myself.If you would like I can open your question up for others here to see if anyone else can assist further just let me know.
