Question about sending units

[winchster]

Ok so here goes.
'84 2.5 4cyl
If the following is the oil pressure what's the one in the 2nd pic behind the distributor?
1st pic is drivers side back of head

2nd pic is behind the distributor passenger side.


Last one. What are all these? Water temp?
Front of intake on top


Back of intake on water inlet and side

The first one should be water temp the second one looks like the oil pressure I don't know about the other two maybe someone with a 4cyl will chim in.

Ok. I thought I read somewhere that the first pic shows the oil pressure. Lol. That's why I'm asking. I'm freaking confused.

Three is probably knock sensor and four the intake heater to help with cold starts. Those are all very similar to the AMC 258 i6 / 4.2l sensors..

First is temp, second is oil pressure gauge, the other two are probaly temp sensors for the comp if you have one. I think one of them shuts the electric choke off.. if theres one on the carb.

1 Coolant temp, 2 Oil press. sender.

3 Knock sensor. If you're not going to connect it, remove it. just an empty hole. No passages behind it.

4 Manifold heater switch? Choke coil switch?

Sweet. This actually makes sense. The manifold heater switch is underneath but those could be what turns it on and off.
