Default What does "B13 TDC P" do?

Hey,
I need to know if that is the correct distributor wire to tap into in install a J&S Safeguard. What does B13 on the ECU do? Does anyone know if that is crank angle or rpm signal? Please refer to the following diagram for clarification.

Nobody has any ideas or information?

I'm going to pick up my motor tomorrow from the machine shop, so I need to get all of these loose ends tied up so next week I can reassemble my whole car....

For 99-00 Civic's, B13 is the igniter control wire which is Yel/Grn.

Hey,
Well on the ECU pinout I got from the Integra FAQ section, B13 is listed as "TDC P" so I was wondering if it varied from year to year or chassis to chassis.

The car is a '92 Civic DX and the drivetrain is from a '95 Integra GSR. Any idea on which wire J&S is looking for?

The Yel/Grn wire has traditionally been used for the ignitor trigger - so that is what you're really looking for.

Hey,
Thanks for the help...

According to th following wiring diagram:

http://tech2.hybridgarage.com/..._obd1

from Hybrid Honda tech articles, the yellow green your talking about is A21, for the ICM. Is that correct?
