Default Wiring cam & crank sensor

i just added a cam sensor to the head and added a gte crank sensor and vvti oil pump, does anyone know how to wire these up?

the cam sensor i dont have a pigtail and the crank sensor i have a red and a white wire


going in a sc300

need to know which wire on the dizzy plug would correlate or direct ecu pin # would be even better

any help would be appreciated

It depends on which cam sensor you added. Why do this anyway? You should be able to figure it out with diagrams. Google search 95 tsrm, use the supra 2jzgte engine control diagrams.

Does polarity matter?? That would make it easy if it didn't

what ecu do you have? if you have a toyota ecu you will need 2 cam sensors. if aem or aftermarket running wasted spark you only need 1 cam sensor. also make sure with the vvti pump you use the tt trigger wheel, not the vvti one.

what you do is you take the distributor cam and crank sensor wires out of the distributor connector.
the black is ground, the blue is crank signal, and the yellow and red I think are the 2 cam triggers (off memory here). what you will want to do is unwrap the harness under the valve cover plastic area and you can actually just peel the wires back for the cam sensor and ground and put a new gte cam sensor connector on it the pins will go right in and should reach the cam sensor spot.

For the crank signal you need to extend the blue wire from where the distributor plug was down to the new crank sensor using shielded wire if possibly, and it also needs a ground wire that will splice into the ground wire that now goes to the cam sensor, and you can make the splice under the valve cover plastics for neatness.

*edit* polarity does matter especially for the crank sensor. you must have the signal and ground on the right sides of each sensor's connector.
if you can look at one on a gte or a vvti ge or gte or a picture of one they will have those cam sensors and you can figure out the polarity, i don't remember which way it goes.

It'll be on a proefi. I'm only going to need 1 cam sensor for the ecu to work according from what I been reading.

So the blue wire + ground to crank and either red or yellow to the cam sensor + ground.

Ive been trying to look for some pics but no luck yet.

Does anyone here have a GTE motor they can take pics of their cam and crank sensor + wire colors so I can figure out the polarity

Thanks in advance

yeah that is pretty much the main part of it, with a standalone you just need 1 cam sensor but you will be running wasted spark and can use either the red or yellow wire for the cam sensor. make sure to match it with wasted spark coils like vvti coils. if you use the 6 gte coils they will not fire as strong in wasted spark and you will need a dli like you would with an aem v1, whereas with the vvti you won't they are meant for wasted spark.

I got some lq9 coils for this build. I've heard nothing but good things about them.
