You will need ep82 sensors for the engine. The ep82 ecu is 2 plugs instead of the 3 on the 91. It's really simple to retrofit the engine loom into the cars original loom. That's what I done on my ep70 4efte convertion
If you pop the plastic cover off you will see the rivets. Both the wires connected to the light live 1 permant and 1 connected to the door switch. Take the wire off the door live. Or add a boot switch
Test fitted the rear brake upgrade yesterday. Need to take a grinder to the calipers and possible a small wheel spacers. But it's looking good apart from that
I found on some it was the actual rivets that holds the contacts inside the light. I scraped round them with a screw driver and every thing was back working again
You need to get management. Then you can adjust the ignition timing down low end and improve respond and fuel economy massively. Even on a ct9 it will work wonders
