humbucker

Hi folks ,
I've been lurking in the shadows here for several years,and finally purchased a 951 last june.

I've wanted a 944 since they first came out ,and bought a 1986 turbo in Garnet red with some minor mods(Basically a Lindsey 280hp kit).

From the searches I've done it ,looks like I neeed to replace the impulse sensor on the drivers side of the trans.

Was wondering how the plug releases from the base?Iam thinking I will try cleaning the connection first and don't want to break off the connector.

Anybody know of a good source for the impulsr sensor?I think the one I found on line was around 105.00$

I thank you for any help you might be able to offer.
