Wire color for wastegate and precontrol solenoids
I am hooking up a boost control kit to my power fc and cannot figure out which connector to plug it into. I have read a bunch of posts that state it is the connector 'without the white dot.' The problem is there are two identical connectors without a white dot. I believe the wrong one is for the turbo control solenoid. I have changed the length of the wires as part of another project so I can't distinguish between them that way. The car has not been tuned yet and I have a 12psi spring in the wastegate so I don't want to figure it out by trial and error either.
If someone with a twin setup could tell me the color of the wires going to the wastegate and precontrol connectors I'd greatly appreciate it.

As stated above the wire colors are the same.
The pre control solenoid is the one closer to the turbos.( as you stand in front of the car, your left) Wastegate is on the right.
that said, if your boost pattern is ok with them hooked up the way they are, then just grab the connector on the left for the wiring. ( And put a new white dot on the connector to the right side!!)

chris are you still in rochester? If so we can run a resistance test on them and do one on my car and match them up I still have one w the white dot and one w/o the dot

I was confused also.. I didn't have a white dot but I could see the remnants of a whiteish band of tape around one of them. (car was made 1/92 so maybe they used tape in early harnesses.) In any event, it controlled boost fine from either of the lines. I suspect that because I had the sequential control in the PFC turned off that this possibly actuates both of the solenoids together so they behave the same.
I ran off of spring pressure only for a little bit (10 lbs) to be confortable that I wasn't creeping and then hooked it up the boost controller. Set your duty cycle low and raise the target just boost higher than spring pressure. Disable the sequential control and try either line. With things set so low you won't break anything if it's in the wrong line. Begin raising duty cycle and see if you notice changes..

You guys are wrong again
The wastegate solenoid has a white dot on it and so does its connector
The wire colors are NOT the same how retarded would that be
The wastegate solenoid wire is blue with a white stripe while the precontrol solenoid wire is green with a yellow stripe (both having a thicker black with white stripe wire as well)

The wire colors AT the connectors are the exact same!! I have 4 FD's in the shop now, one of which is getting a brand new harness.And the connector colors are exact.Unless in my old age my eyes are really that bad I can't tell on a new harness. ( other than the white DOT, which by this point in it's life has most probably worn away on the original harness)
The wire colors at the ECU are as follows from the wiring diagram(Z32): Pre-control solenoid is L/Y ( blue with yellow tracer) and the wastegate is L/W ( blue with white tracer) All solenoids share a common ( B/W) Black with white tracer wire for ground. So i guess go to the ECU since that is where you want to tap in at anyways. If you are going single turbo you don't eed any of the solenoids from the twin set-up.
FYI: Yanni I think the G/Y you are refering to is the Purge solenoid valve
Also i looked at my harness. I have the PFC and had the AVCr ( POS) hooked up thru the harness. I will check those colors again as soon as I can find the damn harness. ( After 2 years of being down I am finding I have "mis-placed" a few parts to the car )

wrong again have your eyes checked!!
All the way out to the connectors one has a white stripe and the other a yellow stripe
yellow is precontrol white is wastegate
Im positive--and yeah I get the concept of the thick black wire being a ground haha
BigIslands I got you this time and I only have 1 FD at the moment in my shop!
But its a really nice one

Thanks for the replies guys. The precontrol wire on my 94 is blue/yellow at the connector. I determined this using Jet7's mazda electrical manual. I connected my avc-r solenoid to it and the pfc boost control function seems to be working fine. Once I get the car dialed in I may hook up my greddy E-01 to see which one is more effective.

had a chance to have another look at the car today and i had wired something wrong, i have the Wastgate control wire on the turbo control solenoid (all 3 are the same) however there is a white dot on the wastegate and i had a very faded one on the wastegate solenoid, so from what i can see this is all correct however i still dont get the charge control actuator pulling in on start up, i took the car for a drive and i get no boost until 4500 then it takes off boosting to about .8 not sure but i think this could be both turbos?
do you think i may have damaged one of the 3 solenoids? guessing is could be the precontrol that isnt working
