Uhhh... yeah reconnected it and didnt seem to be any different, however it has to be doing something or it wouldnt be there.

OVP is a MB new replacement. Same one as was there originally. (red top)
There is a relay next to the OVP... Anyone know what that is for? I searched the forums and couldnt get an answer.

I thought all those symptoms were related to OVP but new one didnt change anything. good thing it was a cheap part.

Here's some info I left out (forgot until after I posted)
1. Early on when the tach was sporadically going in and out, I took it to a local mech and he said it could be one of the round electronic connectors on the drvr side wheel well. At that time, I tapped it with a screwdriver and instantly got it working again. It would work for about a month at a time... then got worse. now nothing. so the AC compressor will not kick on, tach out, kickdown/passing gear not working, and ABS light always on.

So now I have no clue as to what could be causing all those problems all at once except the OVP but I replaced with NEW and still nothing.

** my biggest fear about this is that without the OVP working (if thats the case) then I could be harming the electronics which may be really bad. $$$.

Help!
