Hey guys,

Have been trying to locate the lead for the starter motor under the dash and in the fuse box. I know its supposed to be purple in colour but i cant locate it to break it and add the imobiliser relay.

Can anyone elaborate on the best place to add the relay, wiring colors, etc.

Could be added to starter feed, fuel pump, etc. The relay i have for this is a 40 AMP.

The car in question is a 1993 280e (W124 with M104)

Cheers

USA cars have a starter interlock relay behind the instrument cluster..

Non US have a jumper wire for that circuit , so that is where you want to add a relay.
I can look that schematic up. if you want..........................

That would be great if you could look it up. Its like trying to find a needle in a haystack !

cheers

Go here

http://mb.braingears.com/124_DISC1/Program/etm_93.htm

click on wire diagrams
click on starter/battery -104 eng

You can put your relay at starter feed -X27 [ 3 prong connector left of brake booster/on firewall between eng/booster]

or, X49/2 connector from NSS [ that should be under dash, above accellerator pedal]
Either will disable starter
