[Craved]

i knwo he was trying to get some info from a supra forum, but couldn't get the pictures to work, never heard from him if he worked it out..

only thing i saw was him start the car and turning the TPS with his hand to make sure everything was working.. lol

[Fangz]

im gonna have a look at the tps of the standard rb25 and c if i can somehow get it to fit the q45

[Fangz]

ive figured out what the wires on the q45 tps are,

does anyone know what the wires on the stock rb25det II are? colours and description

craved- i found my information from a supra forum 2, pretty useful

this is what i uncovered so far

on the q45 tps- plug that runs off the tps

Red is the 5 volt input wire

White is the TPS signal wire

Black is the sensor return wire

so i need to know-

1-what wires to match these to

2-also the second plug (wot) of the q45

cheers,

craved, your a legend!

pauls site helped alot (cheers paul), so now i know all the wiring on the rb (WOT + TPS) and the tps of the Q45. but i still havent got the WOT diagram or wires of the q45

its a 3 pin plug which would include:

1,throttle valve switch(idle control point) IDLE

2,throttle opening output signal SIGNAL

3,throttle valve switch (power supply) FULL

ANY IDEAS PEOPLE?

Help would be muchly appreciated. I have one in the garage and i need wiring help for when its about to go on:)

[carl h]

the plug on the tps body is for wot and idle.

take a multimeter and have at it, center pin is common ground for the two so from what i remember if the tps is face 'down' (brass bit down that is) then the idle is on the left of center and wot at the right of center...

i might have that reversed lol...

Here is the diagram guys.

Very simple

In the picture and diagram it illustrates the way it sits in the car attatched to the plenum which should be always upside down to suite the throttle cable layout but it all depends on the plenum.

But to under stand which way the vertical wires are on the plug.

So from top (bonnet side) to bottom (ground side) on the plug

Green

Black/White (Can also be just black)

Red

cheers,

fangz

We had a custom one made up by a shop on the Gold Coast.

Sounds funny but most large Boat shops can make up throttle cables.

You just tell them the throttle cable length you want and how much inner and outer lenth you want for the sleve.

Wgich is what we did.

Some ENZED's also are able to do them.

[mac71]

I would also like to know about the throttle cable...is the stock one used?

As well as if the diagram above is applicable to rb26 motors?

and +1 for a sticky or archived
