I have a 91 teg with a ls/vtec swap. I am using a b16 ecu and need to know what wires to jump to see what the cel code is.

 

If it's an OBD0 B16 ECU, it should have a little window on the top with an LED underneath. The LED will flash out the number of the CEL. Do a quick google search an you'll find CEL lists and full instructions on how to decode the number sequences.

 

The ECU should have a lil glass eye with a red LED in it that you can count the flashes.

 

Thanks. I will look and see
