redtop in s14 ac help..Ghetto rigged.. Pics.. help..

[BillyTheChamp]

well.. i bought my car with the sr redtop swap installed already.. anyway.. the douche i bought the car said the ac was blowing ice cold and he decided to remove the ac belt.. so i check the ac system and it seems that everything is connected.. (but what is this weird metal canister that is attached to my compressor? i tried to wiggle it and it is pressurized and hissed when moved).. hoping for the best i tried to install a belt (as impossible as it was to take off the powersteering belt with that canister right below it).. and when i put on the ac belt and started the car and ac the center wheel on the compressor did not spin.. so im confused.. i know wiring from a red top to a s14 is tricky.. please some one help.. vegas is a hot place..

here are pics.. first is of the lines that are connected to the condenser and the compressor.. the second is the strange metal canister below my ps pump and above my compressor..

that "canister" you speak of is part of the low pressure line. This is why when you wiggle it, R-134a hisses out. BTW, you shouldn't be able to wiggle it and have the R-134a hiss out. That either means your bolt is not tight enought or the o-ring needs to be replaced.

Also, in order for the center part of the compressor wheel to spin, you need to engage the magnetic clutch in the compressor wheel. To do that, you need to figure out the wiring. A lot of people recommend splicing those two (i forget which ones) at F3 plug but that didnt work for me.

What I did was hook up a manual switch to ground the ground wire at the tripe pressure switch which engages the AC relay and sends 12V to the compressor wheel to engage the clutch.

Make sure you bump up your idle as I had trouble with my car stalling during decel with the AC on.

wiring the A/C to work (one of the more common swaps, S13SR into S14) required connecting Yellow/Black to Black/Pink on the KA's F3 plug. That takes care of wiring,

where is the Yellow/black wire located?
