Nice and clear now.
Considering its ld just after 3am i thought i would have another look at it. I measured the two green and have the correct 5ohm reading. Then i flicked the switch and have 18ohms on the resistor side. All looks to be in order. Now for the re install which will happen in a few hours. Fingers crossed it works. Thanks for your tips along the way. Regards |

If it works thats great, looks like you are wired right by the sounds of it. IF it doesnt work then itd back to the drawing board I guess

Tried and tested but no cigar.
Can someone confirm the colors for pins 29 and 30 on the TCM. Im assuming they would be the same on E Series V8's. Will remove for the moment. If anyone has any joy with this please post. Regards |

I've played with EB ED and DL TCMs on and off for about 6 years. The wire colours are nearly never consistent and vary in colour. Your best bet is to look at the plug diagram and use that.

Yep followed the diagram. Resistor gets warm thats about it. Shift firmness hasnt changed at all with the unit plugged in.
Is there a way to test eg just placing resistor on its own between the wire that has been cut to see if it makes a difference at all? Just want to see if the shifts firm up at all and then go from there and see if i can get this working.. Regards |

Well yeah you can take out the 18 ohm resistor all that does is give the gearbox something to go back to otherwise it goes into limp home mode. Working on figuring out what resistors you need mate, bear with me.

No probs looking forward to an update. Keen to do this.

Ok here is an update. I had a play with the unit this arvo. Finally success.
What i did is found some old pc powersupplys that i was going to bin ripped them apart and found some 5 ohm resistors. I added them to the circuit where the adjustable pot lives. What this has done is increase resistance up to 25ohms. Fitted it to the vehicle and the thing shifts harder and chirps the wheels without much effort and not heaps of throttle. (Turn it off in the wet  )Will go for a drive to jaycar tomorrow and have a look if they have anything in this range and do this properly. Big thankyou to 93_eb_fairmont for posting the schematic and the tips along the way. Another thank you to the police officer who didnt pull me over whilst i was testing. I didnt see him behind me lol... Regards |

Champion of the year award goes to wrexed03 for testing it out and finally getting it working. I knew it was gonna be those pins and I knew itd be that pot causing problems but good on you for taking the initiative and getting it working. Let us know if you get a pot that does it right and post up the part number.

No probs will post once i find an adjustable pot that will do the job.

Ok fellas went to Jaycar this morning they dont have a larger potentiometer 20-30ohms should do the job to make it adjustable.
What you can do if you want to make this kit is replace the potentiometer with 2 or 3 10ohm 10W resistors and connect them end to end. I am running 3 of these. The shifts are firm and it chirps the tyres no probs in pwr mode. In Econ mode its still firm but not as agressive due to the earlier shifting. You can turn the unit off using the switch as well if it gets too much for you. Follow the diagram above on the basis of using the resistors connected end to end instead of the potentiometer. Dont forget to turn it off when it rains. There is a very good chance that the back of the car will slide because of the firmness. Parts list i used is as follows. 1 x 18 OHM 10 W RESISTOR Cat No. RP3975 3 x 10 OHM 10 W RESISTOR Cat No. RR3352 1 x DPDT Heavy Duty Toggle Switch Cat No. ST0575 1 x Black Enclosure to house the components Cat No. HB6013 You can choose your own but make note the resistors in the kit are large. Finally if you attempt this and you mess up your car i will not be responsible. Resposibility falls back to the owner of the vehicle. The above has worked on my 1997 NL 5.0 Fairlane i would expect it to work on other E series V8's which use a TCM under the dash. Best Regards Wrexed03 |

Any chance of putting up a diagram with this setup?.

See page 1 replace the pot with resistors. Just solder them together. Two wires that go to the pot now go to the resistors you soldered together. (Resistors should be soldered end to end).
Hope it makes sense. |

Yes, they will look like this
---[|||||]------[|||||]------[|||||]--- End to end - ie: in series. No it doesnt matter which way around they go. Yes youve got the right idea with your diagram. Sorry I havent been more pro active but I just cant be bothered because people are still starting new threads about it instead of searching. Good luck and tell us what car you are putting it on
