Question for the hands on experienced!!! 
Motor 1999 Merc 350 Mag MPI MEFi 3, Merc Distributor
There are 2 ground wires with ring ends on the back of then engine (flywheel end...i keep forgetting what is front and back..on the motor too. any tips? wink)
Without cutting open the wiring harness, could someone tell me where these 2 wires lead?
I'm testing conductivity and one of them goes to the ECU J1 but i'm not sure where the other one goes.
The real problem is i have a high idle and it has been debugged to the point that the TP wires have a short.
I have the Service Manual downloaded and also own the Seloc but wiring diagrams don't say where the grounds physically are connected.
Thanks a million.
