Need help from TEL chassis wiring guru...

Sorry fellas but I gotta post here and get this fingered out -

92 laser - windshield wipers and pisser won't work because amidst my hacking I eliminated the relay which resided on the driver's side wall behind the driver's seat.

I called the dealer and the correct relay is MB510925 -

w/ plug the wires coming out of it are:

Blue w/ red dash
Blue w/ white stripe
Black w/ Yellow stripe
Black w/ red stripe

Upon connecting these to the chassis harness I have no wiper luck with the key in the on position. At one point in the rats nest I removed (I still have all wiring) the blue w/ red dash wire goes through a connector and turns to solid blue. I have been pissing around with these wires for a couple hours and well I'm kinda ready to ask for help...

I have tried grounding out each wire independently from the others, in case one was a ground, hell I tried grounding them in pairs too.

I think something is amiss - from the remains it appears the bl/red and bl/yell wires ran directly up under the dash - but whotheFknows...

thanks for any help - no hate comments please - this car has a purpose, just not quite ready to be w/o wipers...
