ok so i converted my b16 rex to obd1 using the jumper harness and i hooked up the blue and orange wire to the toggle switch so see what codes im throwing and when i hit the switch nothin happens as in the check engine light doesnt flash like it says its suppost to and my cel just stays on so now i cant check the codes anyone have this problem before using a p30 ecu

 

Are the connections of the wires solid? Is it a known good switch?

 

you just need to ground the orange.. thats it
