SweetBadger 91 Posted May 17, 2008 Hi, this has probably been covered before but I haven't found what i'm after with a search... I've just finished shortening a BX16v 3 row loom (by about 2m! ) and I just want to make sure I've taken care of all the necessary connections as it's different to the 2 row mi16 loom it's replacing. So far I've identified the following wires that will need connecting to the 205: Rev counter - goes from -ve side of the coil Permanent +ve feed - thick blue wire Fuel Pump - comes off one of the green relays Switched +ve - goes directly to the large yellow wire on the ignition loom Am I missing anything or is that it? I'm surprised the switched +ve doesn't go directly to a pin on the ECU... Also where can I find the wire for the k-light on this loom, or failing that does anyone know which pin it is on the ECU. Thanks, Alex. Share this post Link to post Share on other sites
pug_ham 240 3 Cars Posted May 18, 2008 Thats it, there are only four wires needed to wire it in. The ecu should get its power from the shunt box connection (often a thick blue wire) & the K light is from pin 15 on the ecu plug. Switched positive goes to the coil plug pin 4 & rev counter is from pin 1 on the coil plug which I is the negative side of the coil. Fuel pump does come from the relays but the colour of these varies, most I've seen have been brown. I haven't wired a three row ecu in but other than the colours that I'm not certain of, it sounds OK. Graham. Share this post Link to post Share on other sites
SweetBadger 91 Posted May 18, 2008 Hi, thanks Graham it's in and runnning, just have to wire in the k-light now. Share this post Link to post Share on other sites
