Impulse Sensor Lead - where does it connect to?

[A1BMW325iSport]

Hi guys,
i have the set of leads with the Impulse Sensor Lead, where abouts does it connect to?

i have looked all over and can`t find where it goes.

do i have the right leads? 1986 325i Motronic ( 073 ECU )

On mine, it runs around the front of the block under the dizzy, and connects to another connector plug that meets under the diagnostic plug..the same place as the crankshaft position sensor plugs in, from here I think it runs to the main loom connector.

Hi A1, Sorry to tell you but you have the wrong lead set, the ones you have are for the later 173 ecu, you want the early set without the pulse lead, cheers Dave

Should work OK though - you've just wasted a few pounds extra.
If you can't change them, just cut the sensor lead off.

cheers, Matt.
