Hello,

I have replaced the damaged stock ECU on my 1995 BMW 318 ti with a programmable MICROTECH system. The new system works great but I have one small problem. With the new system installed my Engine Temperature Gauge and Gasoline Level Gauge on the dashboard no longer work properly. They fluctuate erratically from zero to full scale. It appears that somehow they were grounded in the original ECU. Could anyone tell me where I can get an electrical wiring schematic for my car OR perhaps tell me how I can solve this problem !!

Andre.

andre, the Bentley manuals for the 318 series have full electrical wiring diagrams for the ti (at least for my 97). The Bentley manuals are a bit pricey (@$60) but woth it, to me, for all they cover (like stem to stern).

hey i have the schematic i need your email to send to you

and the year
model
of your car
