Good morning all. New poster, although I have gotten lots of good advice from this site already. Thanks. I replaced the injection pump and heads on my 94 GMC Suburban, and all was going well, but I have two plugs left over (!) They are both from down near the injection pump on the passenger side and I can find nowhere to plug them in ? I have attached a photo of each. The engine is a turbo 6.5 with a pmd relocation kit.

thanks for any help!

First pic goes to Crankshaft Position Sensor,other end of harness starts inline with crankshaft on drivers side of timing cover and needs to be routed up past water pump.

Second pic is of Optical Sensor electronic noise filter and I suspect the rest of the harness that connects to the Optical Sensor on top of the injection pump.

Excellent, just what I needed. The crankshaft sensor plug had gotten lost, once I knew where to look, got everything connected up and started it right up.

Thanks again
