Hi I am after some info please. I am currently fitting an RB20DET into my 180sx. I am rebuilding the engine as a freshen up so I am a few weaks away. Anyway what my question is regarding the resistor that has 2 wires out of it that is placed up on the passenger side strut tower. What is it for? The reason I ask is after looking in some magazines and looking at S13's with RB's in them, this resistor is in place. The fella who made up my loom so it plugs into the 180sx plugs, say's it is not necessary....But after seeing it in place on other cars has got me a little worried. I don't want to finish my conversion, plug in the harness then boom! Something blows up, I won't be happy! So if someone can please tell me what the resistor is for it would appreciated. It sits in the R32 (I have still got the resistor as I removed the harness myself and sent it to him) in the middle on the passener side strut tower next to the turbo. Thanks
