Aftermarket Electric Fans Into R32 Gtst

[r32rb26/30 gtst]

Morning all.

ive searched and searched for awnsers so here goes..

mocking up aftermarket fans to my car and its come to wire them up.
am using a link g4 so was going to have the ecu controlling them,
my plan is to use my original a/c wiring and relay for the fans.

this requires me to bride my A/c pressure sensor in order for this to work.

So im trying to track down wiring diagrams to find where the pressure sensor plug is located
as a/c was removed prior to me owning the car.

If anyone could point in the right direction or if anyone knows exactly where the plug is located would be great.

cheers

If the Link can control the fans, then use new dedicated wiring / relays. Much simpler.

okay what dedicated wiring and relays would they be?

Whatever you create for them will be the dedicated wiring.

thats the thing im not adding, im trying to utilize wiring thats already there. sorry should have been more clear.

to do this i need to know where the a/c pressure switch is, with this bridged i can just trigger the a/c relay @ the ecu to activate my electric fans.

i can only find r33 ecu wiring diagrams are they the same as r32? also anyone have a.c still hooked up and can give me a hint as to where the plug for pressure switch is?

Is the stock wiring up to running some big electric fans?

I doubt it.

[r32rb26/30 gtst]

tuner tells me he uses this method all the time but he couldn't remember what colours the wires are all he could tell me
is that the wiring (for the pressure switch) is around the front headlight area. (hes a busy guy)

Il be doing amps draw tests etc once i find this pressure switch anyway so il find out

please don't comment on my post with unnecessary statements. unless your trying to help.

[Ben C34]

Do you consider my comments unnecessary?

Wow.

I didnt kow there was some kind of check I had to do or standard I had to meet. I think you will find comments are helpful.

In the amount of time you spend researching and stuffing around to use the old wiring (which may or may not be up to spec) you could have run a couple of wires, a relay and a fuse and be finished.

[r32rb26/30 gtst]

not all of your comments just the one saying "Is the stock wiring up to running some big electric fans? i doubt it"

do you actually know this for sure?

how does that help me at all? i do find it unnecessary sorry if that offends you. all im after is help.

yes i agree, i could just add wires and relays and a fuse but that's not what im doing.

As said im utilizing wiring that is already there, the wiring may or may not be up to task il be figuring that out once ive found
this lovely pressure sensor. instead of just guessing

I think you've misunderstood the instruction from your sparky.

As Ben replied, the wiring from the aircon dual pressure switch is quite light, just sufficient to operate the aircon relay and way too light to run a high amp draw thermo fan. (The pressure switch is mounted on top of the receiver/dryer)

The wiring to the compressor clutch however is a different story, is quite generous in size and is what I think your sparky was speaking of.

As for wire colours, forget it.

Nissan have a million colours and when they've run out or colours, they start adding coloured stripes.

Nobody has the same colour sense, your lilac might be my blue, which is why we use multi meters.
