Full Version: changing Ob1 to Ob2?
6G Celicas Forums > 6th Generation Celica > Interior/Audio/Electrical/Wiring
I was wondering if anybody has converted ob1 wire/DLC to OB2 configuration or is there a company that offers that service? Any info help thanks?
It's not just the wire - the ECU is different, and along with the ecu the distributor and engine wiring harness. You would need to change all those components to go to OBDII. I think OBDII cars also got crank position sensor whereas OBDI had it all in the distributor, but I'm not 100% certain on this one.

In other words, forget about it...
It's not that easy cos of all the work you need just to convert it
what car, what engine, what year? what level of expertise do you have?

i went from obdII to obdII with Canbus
