alright i read about it that u have to jump the big electrical connector on this post that is on the faq http://www.mx-3.com/phpbb2/viewtopic.php?t=41847 , but then i read u have to jump the white connector on this post http://www.mx-3.com/phpbb2/viewtopic.ph ... =auto++ecu, but the post on the faq doesnt say about that one!?, do u do both or which one? or does it matter!?

btw, is the switch behind the clutch pedal for cruise control disengage?, i know the one in from of the pedal is the clutch switch.

I'm sorry I can't answer your first question. The the switch your talking about it more likely the neutral safety switch, it's a switch that needs to be depressed to let the car know that the clutch has been *fully* depressed and to allow the car to start. FYI, it does not disengage cruise control. I know you can shift while on cruise to help out the motor, I know, I've done it

alright, thanks mate..
i never had manual car with cruise control, so when u press the clutch while on cruise control, the engine doesnt rev all the way up or stuff like that!? and it doesnt disengage when u shift!?

oh according to the online shop manual thats not the neutral switch, neutral switch is somewhere under the distributor cap, according to the online shop manual. !?

You only want the white one.

I think that is for a 94+ or an 96 model once it switched to OBD II

The white connector is for the clutch safety switch. You can jump it like Perry did or you can hook it up to the switch behind the clutch pedal and be proper about it. This way the car will only start when you depress the clutch pedal. The second Yellow connector is supposed to be a pin out connection to connect your reverse lights switch up to the factory ATX harness. Problem is.. the pinout in that thread is for a PGT or MX6 car and not a MX3. So there are differences and you will need to experiment with the connector or wire the reverse lights up separately (which is what I did).

alright, ill try that.

the reason i was asking is cuz, the car i bought was converted from atx to mtx, the car cranked fine the day a i bought it, but then when i tow it home, the car wouldnt start from the ignition switch, i thought he had this connectors jumped and they fell off with all the vibration, im gonna check into that today.

ps. oh and btw, so the automatic chassis harness comes with mtx connectors, like clutch , neutral switch and allt hat stuff?

No it doesnt come with connectors.. if it did.. you wouldnt have to be splicing or jumping connectors to make the clutch safety switch or reverse lights work.

mmm no its not.

My car will start in any gear- whether the clutch is pressed or not. So, you gotta be REAL careful when starting the car!

LOL

Thats the point Perry.. if you had connected the plug to the switch on the clutch pedal.. it would NOT start UNLESS you had the clutch pedal pressed down. Since you just put a jumper wire into the plug.. you bypassed that safety feature.
