Probably in the wrong thread but I just bought my first yota and need some help with a wiring problem. It's a 22r-ec that I'm pretty sure I have the harness in correctly I've run into about ten wires that go from the computer to the firewall to near the battery. They we're cut by the previous owner and I can't track down where they go. I'll post pics tomorrow but there is three white wires and three blue w a brown and another that I'm not sure where they go. Also where the manifold bolts to the block below the carb I can see gasket and into the block... I'm thinking that it's the wrong manifold? The previous owner said it ran but I'm skeptical with that whole in it... Any advice or good directions to parts would be awesome, thanks guys!
