Installing a Haltech Nexus R5. REALY liking the idea I can use the DBW function now.. Silly me I bought a GM LT5 throttle body.. It has pinout of Motor +, -, Throttle position Sensor (SENT1) signal, low reference and 5v Reference..

ECU has Motor +,- Sensor ground, 5 volt ref, TPS 1 and TPS 2

I believe I know the answer to this but I'm hoping all my machine work to make this throttle fit isn't for not..

Doing some digging on this I have found a company that makes a signal converter JUST for this. What's the thought on using this technology?
