Hi Andrew,

First, download this file: https://www.4x4community.co.za/forum/attac...1458330603

And then search for “Connector: C1040L” this will give you ALL the pinout numbers of the plug.

Then download this file: https://www.4x4community.co.za/forum/attac...1458330603

Scroll down to page 74, you should see the relative part of the circuit diagram. J100 (in this diagram is the C1040L connector) shows C1040R-3 and C1040R-4 the two wires that you need to link.

Hope that this helps

Remove the instrument cluster plug, and with a paperclip or similar bridge pins 3 and 4. Leave the plug out of the instrument pack and see if you can now start properly.  1988 90 Td5 NAS soft top Cool

Hi Martin,

Tried the bridge and it started 1st time. now to breakdown the cluster to check the solder as per Andy's suggestion. Keep you all posted,
Andrew

Dear all

Following the tip from Martin, I had all the connectors soldered as well as the can chip and main chip. No luck... Big Cry

Tomorrow I will create a permanent bridge between the wires, not sure if there are any long term risks with this fix, but I will be able to use the car.

Thanks to you all for your support - it's great to know that there are folks out there that are willing to provide support to others. Thumbs Up

Andrew

Hi Guys, Bridge the wires today and car starts every time. One thing is that I have lost all gauges and some of the engine warnings lights, milage etc. I have only cut the wires and joined them together before the Cluster plug.

I just wonder if they should still go through the plug to the cluster and be bridged- but this doesn't seem right to me???

Im not sure - but maybe the chips have been damaged during the soldering.

Thanks for any thoughts

Andrew, post up a photo of the gauges with the ignition switched on please. I think you may had lost the permanent power feed.  1988 90 Td5 NAS soft top Cool

Dear Martin,

Went out in the dark and made a quick video (not quite Quinten Terrentino), but it shows how the dash board looks



Thanks for your feedback.

Andrew

I've not had a chance to try to make my spare instrument pack do this, but I think you are missing one or more of the power feeds. The hard-wired signals work (illumination and indicators etc) but anything involving the microcontroller aren't - fuel gauge, engine warning lights.

Check fuses 5 and 15 under the steering wheels just in case these have blown.  1988 90 Td5 NAS soft top Cool
