where this plugs connected?

[markus_74]

I got problem to identify this plugs there are about 5 same plugs 3 pins like this and as I know only 3 is that is for tps, icv, cps? And 2 another I don't know

[sweep]

The 2 at the side of each other look like -cps and pulse sensor from plug leads and the othe icv?

[gromgsxr]

tps, icv, crank sensor, plug lead sensor, oil level sensor

[markus_74]

thank you for the info, but how can I know which plug go to crank sensor, plug lead sensor it look like all is same? and which to tps (maybe the one that has dirty oil?) and icv is the clean one?

[gromgsxr]

if you pull back the rubber boots the icv has a white with green stripe and a white with a yellow stripe its on a longer cable from the rest, the 2 together are crank and plug lead sensor wires, i think the tps sensor wires are: brown, brown/blue & brown/black. and the last oil level sensor

[markus_74]

does cps plug and plug lead sensor wires is both same I mean it is interchangeable? or if i false to install it the engine will not turn on?

also I read that I should connect earth wire from oil sump to ...? engine block? or car body? I'm difficult to located specific location and do i need to connect rear alternator with earth wire to ...?

thank you

inlet side of engine there should be a m8 bolt hole for the ground strap to the chassis. the cps + plug sensor wires are identical if you put them round the wrong way there will be no spark from the coil and the fuel pump will not run so if that happens switch them, or you could continuity test them to see which is which back to the ecu plug, the wires under the boots are identical on them.

still not clear about the ground strap point and where should I connect it, I have search in the websites and also in the forum, hope to get clear explanation or pics, but no info.

I'm very afraid if my wire will be fried because forget to install this ground wire.

the info I got is 1 of the ground wire strap is on the top of oil lump but I don't know where it should connect? oil lump to chassis? or oil lump to engine block? and where the other ground point?

[sweep]

Earth strap links to sump near to the level sensor

[markus_74]

yes, from the sump near level sensor connect to ...? (alternator (-) or to any chassis near it, or to engine block?)

I have search this info but still not get.

[sweep]

Chassis should have a block with a thread on it

[markus_74]

thank you sweep, I will check on monday. does the ground/earth point only this one on m20? or there is another?
