western Posted November 23, 2012 Share Posted November 23, 2012 IIRC there's nothing in the Td5 instrument pack conversion to stop the ign/engine starting, maybe your start relay is dead or you've dislodged a connection on the ign switch terminals.

fireblade7 Posted November 24, 2012 Author Share Posted November 24, 2012 once i do the dash temp mod using the full td5 wire harness does the temp wires change at engine end ie pink/black or pink/green????? regards mike Quote Link to comment Share on other sites More sharing options...
fireblade7 Posted November 26, 2012 Author Share Posted November 26, 2012 i have done this mod to temp gauge but i cant find the green blue wire for the sender goes down to multiplug at dash from the other side of plug i expect it to be in the engine compartment no not there . so i think i traced it to ecu plug under seat it shows power am i right in all this the temp sender at engine side is pink/black and pink green????????

fireblade7 Posted November 26, 2012 Author Share Posted November 26, 2012 i have done the temp mod but cannot trace blue/green temp wire ??? after it goes down to grey multiplug and out cannot find it at engine end using complete td5 wire harness i have origanal temp wires pink/black and pink/green i left them in cut every thing i didnot need does it change to pinks ?? opened loom again and cannot find greeen/blue in there but i think i found it down at the ecu multiplug am i right hope people can understand ?? regards mike Quote Link to comment Share on other sites More sharing options...
western Posted November 26, 2012 Share Posted November 26, 2012 (edited) what do you mean by using the full td5 wire harness ijust the instrument pack harness or a complete Td5 dash/chassis harness, ? if just instrument pack harness, all the info you need to make it all work is in http://www.retroanac...a-200tdi300tdi/ my 110 has a td5 instrument pack & it went in with no major problems. I just connected the existing dash harness to the instrument pack, no need to touch any no related wiring.

fireblade7 Posted November 27, 2012 Author Share Posted November 27, 2012 i used the complete td5 dash wire harness engine and chassis harnesses i have only done the MOD FOR TEMP ONLY for 200 tdi the problem i think i have is the dash GREY MULTI PLUG where the green/blue temp wire goes and comes out the other end is live and i cannot find it in the loom going to engine the temp wires at engine side temp sender are pink/black and pink/grreen origanal ??? from td5 loom i think i have traced the blue green wire at the multiplug where the ecu used to be under the drivers front seat td5 hope this makes better sense regards mike Quote Link to comment Share on other sites More sharing options...
Les Brock Posted November 27, 2012 Share Posted November 27, 2012 Mike, So you have run a new ign supply to the injector pump solenoid ? and the TD5 loom uses a switched negative for the starter relay coil, via the alarm ECU/immobiliser IIRC Quote Link to comment Share on other sites More sharing options...

db950 Posted November 27, 2012 Share Posted November 27, 2012 Hi Mike Don't bother tracing the wires in the looms. If I've understood you correctly you have modified the dash/clocks wiring as per retroanaconda's guide, if this is right then run a wire direct from the back of the dash (green/blue wire) straight to the temp sender on the engine. In the td5 loom the temp signal goes via the ecu under the seat but no need to use these wires. Quote Link to comment Share on other sites More sharing options...
western Posted November 27, 2012 Share Posted November 27, 2012 heaters for engine I haven't had hands on one of those heater units, so can't advise on how to connect it to engine or wiring. Quote Link to comment Share on other sites More sharing options...
