I need to know the physical location of the vtec solenoid and pressure switch on a 93 del sol. Also does anyone know what the 2 pin sensor is to the left of the distributor and attached to the rear of the engine? To the left of it if your standing on the passenger side of the engine compartment. Its a round green colored sensor, and there is another sensor to the left of that sensor with just one wire. I have 3 wires in my engine wiring harness that were cut, taped and jammed down in the harness when i bought this car from a junk yard.

 

If its a 93 its either an S or Si. If its an SI the solenoid is on the left hand side of the motor, between the intake and motor itself (closer to the motor) its quiet obvious as well.

 

The solenoid and the switch are right next to each other. The pic above shows the whole assembly. The large round hole in the center is where the pressure switch will go. The piece above the clip is the solenoid. It sounds like the sensors your talking about are the fan switch and the coolant temp sensor. We would need a pic to see exactly though.

 

Nah cant be the coolant temp sensor, those are lower right at the coolant outlet. But the sensor im worried about is the same shape as that coolant temp sensor, same 2 pin connector. Now, in the pic there is only one wire shown, same as what i have on my solenoid/pressure switch, my schematic shows 2 wires? Im using a CHilton manual. Wish i could get my hands on a full schematic from honda. I converted this car from an automatic to a manual.

 

I know its a b18c but you get the idea

 

Right where that vtec solenoid sits, its right next to it, like almosts literally part of the solenoid. Round with 2 pins. Ill take a pic of it and post it or try to post it tommorrow morning. I have 2 other connectors and cant find a sensor to plug them to. Ive accounted for mostly everything. I say most because i dont know where the barometric pressure switch even is. Ill post a pic of them also.

 

Yup that green one is exactly the one im looking for. Damn it is the oil pressure. Now my next concern is i found 3 wires cut taped and jammed in down in the harness, 2 of those wires go on that oil pressure sensor but dont know which 2. I imagine one is a ground. The 3 wires i have, one is a black, which is a ground for something, the other is a green/yellow and i dont remember what the other one is cause im not at home looking at it
