I just got the price for a new speed sensor from the local OPC: $257.46. Ouch! Any ideas?

Also, can anybody give a good description of what exactly the two speed sensors atop the bellhousing do? I know the one in the rear picks up the flywheel, but what does the one in front read and how do the two work together???

arent they the same type of device as the electro-magnetic pickup as in the distributor , it senses when the steel tab passes . I know the pickup for a 79 mutang distributor cost $8 . maybe someone with electrical knowledge can take a closer look and see HOW similar they are . if they do the same thing in the same way , it would just be a matter of mounting it .

you might even be able to REPAIR it , this link is for a bike pickup coil but the failure is probably similar .

One is a speed sensor for fuel management and the other senses TDC for timing. The third sensor is for testing.

LOL

Thanks for the tip, Paul.

I think $24 beats the hell out of $257, eh? It's a great deal if it works and if it doesn't, well, at least I didn't spend a fortune for it.

Okay, I'm in the final stages of buttoning this engine compartment back together. (Finally) As I was re-installing the bracket for the two engine sensors on the clutch-housing, I realized something I had overlooked during the removal process: The single wire that goes to the bracket -not to the sensors- was never connected to anything. In fact, it has a rubber cover over the connector-end. Anybody know what this does and why it would be an optional connection?
