Or just wrap some appropriately thick magnet wire around the sensor and put it in series with the injector lead.

Aye, hooking the sensor lead up isnt my issue.. thats easy.. My problem is the supply. I dont want to burn the sensor up and it says 20mA max current to the sensor. the sensor has to have power to it before it will read the current in the injector wire. It is a three wire sensor similar to TPS sensors.
I know my battery is rated at over 600cold cranking amps. Im rusty on some of my electronic terms but it would seem to me that 600 amps exceeds the 20mA rating,,,,, just a little. To my way of thinking the supply should come on with the accessory link when you turn the key. I would really rather test this on the bench first though. Either way if my thinking is correct I need to limit the amps to the csla2cd first. not sure how. resister? fancy diode?
