Auto to manual conversion

[RyDog]

I spent a few hours on my back and came with the idea of ditching the auto in my '94 Bighorn.
Good idea?

Well it goes a hell of a lot better but will I get another WOF because of the wielding for the new cross member mounts 12 odd inches further forward?

Aside from all the stress in finding bits and bobs to match it all up, I got there and like the drive now but the question is......

HOW THE HELL DO I GET MY REVERSE LIGHTS TO WORK AND WHAT WIRES WILL LET ME TAKE THE KEY OUT??????

I managed to arrange the wires from the selector to start but that's it!

Any knowledge in this area would be a great help.

Dont weld directly to the chassis Make an adapter mount If you weld the chassis you visit the certifier. The park switch was in the auto selector. Its just a microswitch. Short it out and the key will work. Reverse lights were another microswitch in the selector. Extend them to the switch on the gearbox

Also a few people are looking at this conversion. A full write up with pictures will be nice
thanks

A little late for that, I was in a hurry so mocked up some plates in on they went.
I have 6months before the WOF runs out so hopefully I will be able to make something up before then.

Will do a write up soon when I have sorted out all the issues.
Thanks for the advice.

I tripped the selector wires but it won't let me have the key......
The reverse lights should work.

looks like im going to have to do the same thing if i cant work out this overdrive flashing light problem.
luckily there are a few threads about it and ive got a mate who has a scanner.

Jellis tha flashing overdrive light is a signal telling you something is wrong two things u can do is find the ecu connector and bridge the outer holes with a paperclip then whilst engine is stopped at running temp then turn on with clip in and watch the light it will give you a flashing code first sequence is tens followed by a slight pause then second sequence is ones fault codes can be found on a website i cant remeber the name but it is easy to find i wrote something on here before on it,
or unplug the actuel ecu and wait 3 minutes and plug back in that resets it becaus eany fault registered either now or in the past repaired or not will show up and maybe it is an repaired fault it think the website is called rennics.com anyway check that site out it explains everything

thanks for that i will have a look this arvo.
i just rang an auto shop and he recons it could cost me 1000's or it could be a really simple fix.
is the ecu connector in the drivers side kick pannel?

there seems to be alot of threads about this. wonder what every ones problems were

[jellis]

sorry to dig up an old thread but, my gear box is in now.
and i need to sort out the wiring any one have any pictures of what i need to connect and to where?

[geeves]

out of all these problems the overdrive light flashing is the easy one. Its not needed any more so ditch the bulb. Problem gone.
Reverse lights are controlled by the old inhibitor switch It should be simple looking at the switch to work out which wire does what and hook the correct wire to the gearbox reverse light switch. The inhibitor switch it 2 parts on a meter long loom.
Not sure on the key thing It might be the inhibitor switch but might also of been a mechanical thing from the selector box

[jellis]

unfortunatly i got rid of my wiring loom with the auto.
dont care about the flashing switch im hoping if i get a manual wiring loom and plug it in it will all work.

Geeves

what do you mean by makign an adaptor plare for the new gear box cross member? I am assuming you mean to make something that can be bolted to the chassis rather than welding it,....

[geeves]

I havnt seen what others have done but a heavy plate bolted to the xmember and supporting the rear mount of the gearbox

Hey guys I've just completed this conversion myself and mechanically the car is complete I'm try to bridge the park inhibitor device currently I have the loom from the little box with the microswitches plugged into its original position under the bonnet and the box with the micoswitches cut off as how I received it I also have the auto trans ecu plugged in I have a 94 4jg2 bighorn anyone know the colour of the wires I need to bridge I currently do not have a multimeter to test for continuity any help appreciated cheers
