I trying to install my RC's right now, and I cant get them to fit into my intake manifold. ('96 GSR) Do I leave my stock bottom O-ring in the intake manifold and use the O-ring that came on the bottom of the injector at the same time. Or do I take out the stock O-ring and just use the O-ring that came with the injectors

 

The instructions say to remove the stock o ring, and install the one provided with the injectors.

The injector won't bottom out, but will seal properly once the fuel rail is tightened down.

 

Thanks for your help man...

One more question. None of the wire colors on the RC's match the wires on my stock wiring harnes.

I dont have the instructions cause I bought them used. Does any one have a pic of the wiring diagram Thanks

 

Your RC's came with a harness? The ones I got were just plug and play. Just install them like your stock ones and you should be ok.
