got a digital multimeter from maplins to help with my instal
, im an engineer not a sparky so may come across as a bit simple
the sr20 det has 2 temp senders one single connector that uses its body as ground the second has two connections and no body ground, found that the have different resistances, the single = 1.208 k ohms the twin = 2.291 k ohms, checked the vems air temp sensor reads 2.301 k ohms so it's pretty obvious that i use the twin connection sensor, but why does the single read so differently, also help on connecting the cas to the ecu would be appreciated, wiring diagram would be great[explained simpler the better
