I had my 4.3 litter v-6 pulled out and a 5.7 litter v-8 installed. when they installed the new engine they did not do a very good job, I think I have just about gotten everthing back together that they did not do. The truck is running rich its a throttle body. they did not hook up the o2 sensor I bought a new sensor installed it in the exhaust manifold on the driver side the only one I seen. but there is no wire hanging in the area to plug it into, I have looked all over for this plug cant find one. does anybody know where I can find this wire or the color code of the wire so I can trace it from the brain box.
