Guys,
done a auto to manual conversion last night and as usual the cruise control now doesn't work.
Has anyone else done this conversion and knows which wires to fudge so the cruise control works again.
Thought i'd ask or ill have to get the wiring diagram out and sus it out.

Same thing happened with my MA70.
You lose the speed sensor which is on the extension housing.
If you can find the pulse rate of the sensor you should be able to get a aftermarket one to make it work.

But the speedo is connected back into the manual, doesn't it reference off that?
When i removed the auto all i removed were 4 plugs,
1 for the overdrive switch inside the car
2 i think is for power for the solenoid for the overdrive
3 for the nuetral start switch which i reconnected to start car
4 for the reversing lights which was reconnected
So anyone have any ideas?

Paul,
Does the cruise control only work in overdrive? If so, the overdrive switch could be the issue?
Cheers

My car has cruise control still working after 1JZ conversion although its still an auto (off the 1JZ). I noticed when I swapped throttle cables over the cruise control worked of the throttle cable. The actual unit on the MA61's has a large vaccum bottle next to the brake booster with a cable going to the throttle and a vacuum hose and some wires. Unless something has been disconnected it should still work. Check the vacuum line is still hooked up. Its a great thing to have on the highway...

The MA 61 May be different than the MA70.
The ECU has a speed sensor which runs of the speedo.
The cruise control has its own sensor on the box(extension housing).
Did one of the plugs go to the rear of the box?

The Mk2 cruise control runs off the speedo (the electronics are actually integrated into the instrument panel), which in turn runs off a conventional mechanical speedo cable. Mk2 transmissions don't have an electronic speed sensor like the Mk3's.
My black Mk2 was a 5-speed that had been converted from an auto, and the cruise didn't work in that either. I could never figure out why, because everything was hooked up correctly.

Yeah its a shame to loose the cruise control.
I think Nishad has an XX Supra that has a manual and the cruise control works also. I'm really determined to get it working as i can't handle any more speeding fines.

When using a cruise control with a manual box, you should have a switch on the clutch pedal (like the factory units) which disengages the cruise if the clutch is depressed. Don't know what man' box you used but an R-154 which i saw had a speed sensor in it's ext' housing.

Paul,
Having looked at the problem closely, this is what I see...
Take a look at the the wire out of pin 11 in your cruise control loom connector.
This wire eventually connects to the positive supply rail through the 15A ECU fuse (and on m/t systems, through the clutch switch, which disengages the cruise control when the clutch pedal is pressed) and connection is spliced from this wire which goes straight to pin 3 of your a/t neutral start switch. The reason why this is connected to the neutral start switch is to cancel the speed setting (and disengage cruise control) when switched to "N"uetral in you a/t. This is probably the problem you are experiencing. If i remember correctly, pin 2 of your neutral start switch connector goes to the starter motor. What did you do with pin 3 of the connector? if the pin 2 - 3 connection is already closed try openning it and see if the cruise control would work or vice versa. Hopefully this should solve your problem.
If you want to, you could connect a clutch switch to the wire 11 out of the cruise control loom connector for the clutch sensing.
Hope this helps...
Oh yeah, and check the overdrive relay connection off the cruise control loom (5) to make sure everything is okay there too.
Cheers
Nishad

T'would have been nice, had access to an import Supra with a 5MGE, manual and cruise control, but it all seemed too hard at the time, I should have at least ripped it out and given it a go

Sounds good nishad. So where is this cruise control loom?
Up under the steering column? Also where is the cruise control ecu? Cou;dn't find the bugger.
Maybe i might come over and we'll see if we can sus it out.

The CC control unit is behind the kick-panel on the passenger side from memory. Buggered if I know why they put it there though!

Kewl, ill have a go at it soon. The wiring diagrams i have are in two manuals and are very vague and different to each other just to make it extra hard!

Ok Ray and i have been looking at it today and this is what we have found and have made assuptions on.
1. Only the XX import Supra's have the clutch dis-engaging switch as no Aussie manual Supras came with cruise control. We even pulled that switch you talk about Nishad on the clutch from an XX and went to put it into Ray's (Aussie manual conversion) but there was no plug for it to go into.
We assume that the looms are different from XX cars with cruise control compared to Auto and Manual Aussie cars.
Also TD42T suggested there may be a separate speed sensor on the extension housing. Found after examining the auto, there is no separate speed sensor.
So i'm lost again.

Yes.
From a 1986 manual (the very last of the MKII before the 1986.5 MKIII)
It was on a US based site, but i dont think the wiring harness would be all too different between the countries regards crusise control?
Unless of course there is a difference between the 5me and 5mge harness for the cruise.
Im running the 5mge ecu anyhow.
