OBDII wiring question

**cjcrazy8** · 07-02-2007, 07:05 AM

I have a 98 5.7 LS1 that I got from a Junk Yard, Unfortunately it did not have the OBDII connector on it. I bought a replacement but it did not come with any instructions on tying it in. Where does it tie in to? Anyone have a 98 diagram?

Don't have a diagram but here's some info on what the pins are/location on the DLC: www.obdii.com/connector.html

If the wires are just cut here's what my helms says about the colors, not sure but think '98 is the same.

Pin 2 - PPL Class 2 Serial Data
Pin 4 - BLK Ground
Pin 5 - BLK/WHT Ground
Pin 16 - ORN Battery Positive Voltage

Thanks man. I dont remember seeing any cut wires. I guess they could have been cut and then tucked inside the plastic shielding. I was also wondering if someone could tell me what the round green connector is. The one that is about the size of a golf ball.
