i have a 98 ls b18b1 and 99 ek what engine harness should i use to pass emissions i have a ls harness and a frankinstiend cx harness and what could i do to make it work .

i would assume you need a obd2b ls harness and ecu. then its all plug n play and if everything is plugged in should have no lights.

modify the stock harness from your car & run a jumper harness with an obd2a p75, unless you have an obd2b p75 with the imobilizer disabled

[LowNsloW]

will jumper communicate with obd port?

jumper harness is just wires u can use to pass if u down grade obd2b to obd2a because they look for same sensors and use the same code reader.
