Default 02 sensor wiring

the connector for the primary is cut off. i have a black\yellow, Green\black, a White\black, and a White wire. I bought a bosch sensor with two white wires a gray and a black. Does anyone know where i can get a connector or simply what wires to splice together. Oh yeah its for an obd2 harness with p28 ecu.

if ur bosch sensor came with a plug the wires should be like this:
1 2
3 4

1-white on ur engine harness
2-grn/blue(looks like blck but its blue) on ur engine harness
3-yel/blk on ur engine harness
4-blk/white on ur engine harness

dont splice the wires try to solder them,i know it hard to reach up there but if u dont mind takin the harnes out itd be the best
heres a link to my thread i just did the wiring my self a couple weeks ago

awesome! u guys are great. If i splice the wires would that give me a low voltage signal on the sensor? I could solder the wires later on this month just wondering how long i can ride with just the splices?

Itll be fine but better to solder for the Long run.I'm not sure it'll give u low voltage signal but it's likely.people splice dizzy wires,its not good but they do it lol and their cars run fine.

I would have NOT BOUGHT the BOSCH sensor, but that's me. I also would not have bought a universal one either.
http://www.sparkplugs.com &
http://www.oxygensensors.com both sell Denso, NTK(NGK), and Walker OEM style O2 sensors for cheap.
