Hello,

I have a little problem with connecting the M&W pro 10. We have connected all the wires but one. The small blue wire is the tach output signal from the ignition box. This will tap into the dark blue wire on your distributor and provide the signal for the factory tach to work. The only problem is you guys use a OBD2 harness and i have a OBD1 harness. What wire should i use so i can activate the factory tach. I can't find any thing on the internet about it. Could you please tell what wire i can use from the ecu or what color off wire by the OBD1 ignition/ Distributor. I use a OBD1 ignition/ distributor.
I hope you can give me a answer back because that's the only wire i have left over to activate the M&W.

The the M&W pro 10 is build in is a Honda civic EG hatchback from 1992 with a P28 ecu. And a OBD1 harness in the engine bay.

Please help me have to go on the dyno about 2days

you can use either the blue wire off the dizzy or from the drivers shock tower.

T1 Race Development Pro 10 Harness instructions


1. Mount ignition box and coil on passenger side, away from main wire harness. Usually between the shock tower and headlight is the best location. The ECU can be very sensitive to RF noise, keeping the coil and CDI box away from other electronics will help considerably.


2. Big red and black wires go directly to the battery, it’s very important that these are good clean connections.


3. Small white/violet and red wires go inside the car to the ECU. The white/violet wire goes to pin A21 – ICM on an obd1 harness. The white/violet wire goes directly into the ecu, and cut the old wire that used to go in, it is no longer used. The small red wire needs to be tee’d into pin A25 – IGP2 on an obd1 harness. This is the switched 12v signal that turns the ignition box on.


4. The small blue wire is the tach signal ouput from the ignition box. This will tap into the dark blue wire on your distributor and provide the signal for the factory tach to work.


5. The short harness with the white/blue and white wires goes to the coil. White/blue is ground and white is positive.


If you have any questions, feel free to give us a call.

Thanks
