TBI speed sensor source

[DaveB]

I need to find a source of a 2 pulse per revolution speed sensor for the TBI in my Commando. I have found them on line but before I order an expensive one I wanted to find out if anyone knew of a vehicle they came on that I could look for in the yards. I could wire up a circuit to divide down the one I have on there now (8 pulses/rev) for the aftermarket speedometer but I don't want to possibly mess up the gauge. At first I thought the sensor in the 88 suburban's speedometer was just for the cruise control so I left it out and now I get error code 24. In the short term I may route a speedo cable in and mount the burb speedo and sensor under the dash but in the long run I want something cleaner.

Some of the 80s fords had a speed sensor that was in the middle of two Speedo cables. Maybe that would work?

I took the suburban speedometer that I had and took it apart leaving only the optical sensor. Hopefully this will work OK till I find a better solution. I would need to find out if the Ford unit has the correct pulse count but it might work.

i believe the full size blazers in the 80s have that sender

i don't know what is "expensive" to you but speedometer solutions in milwaukee manufactures the inline sender so that you can keep your existing speedo, just tell him the year/make/model of the ecm, and what vehicle you put it in and he can do it, i've used them to supply me these in the past, they work well

Dave, check out Classic Dash, they have some stuff to adapt to Autometer gauges-- here's a link for the PDF for 73-87 (and up for the square body trucks ) and also to their misc. products-- pigtails and whatnot.
