HOWTO:- Fit cruise control to a Sprinter 312D, 208, 210, 310, 308, Diesel models. I suspect petrol is very similar.
Its not that difficult -
* remove steering wheel. (27mm socket, undo, yank at top of wheel - LEAVE NUT ON! or get a steering wheel in the gob)
* remove plastics under steering column
* remove plastics over column (two phillips - ideally need short screwdriver)
* remove fuse box (1 bolt at bottom, swing and un plug)
* remove switchgear (two phillips screws)
* clip cruise control lever on.
* do up screw from behind (new one you bought in the kit)
* feed wire down LHS of column
* attach red/black wire to red/black wire of middle plug (6 pin) on fuse box. Just solder onto lead if I were you.
* undo nut on brake switch (17mm spanner) - just loosen it. (I found it easier to see by removing the RHS dash plastics where the fog switch is. pop out black switch panel, 1 screw under, two more at bottom, rest just yanks out)
* pull switch out of RHS of bracket
* unplug T plug
* push out - (of T) pin (three colour iirc - black, white blue?) NOT I (of T) pin (brown?)
* cut off old socket, splice in blue and white ? wire into original loom, re-crimp on socket and re-insert to T socket
* attach two small plugs to new brake switch, and old T socket.
* put switch back onto bracket, not forgetting fat aluminium washer thing off old brake switch!
put all plastics etc back together.
* feed 6 wires to ECU. Discover that ECU is on LHS, this is a LHD loom. There is no RHD loom. Realise you will have to extend the wires 5 or 6 feet.
* remove L:H headlight. (remove indicator by holding clip on inside, push out, remove light by 4 screws, 1 behind indicator, 1 behind grille, 2 on slam panel)
* ECU plug is directly under the battery (
seriously - who in their right mind puts the most expensive, delicate piece of electronics under the acid filled battery, right next to the leaky headlight, right next to the hot humid auxillary heater? Prats! ).
* Realize that the plug is basically glued onto the wires. Order a new backshell, seal and front shell of socket. Order pin removal tool
e.g here. or nick a pair of tweezers off the other half and grind doiwn to make a tool...
* cut off backshell carefully.
* remove all 30 odd wires, noting their posistions,
* re-insert into new socket with new wires in place (numbers to be confirmed)
Will edit this as and when I get the numbers for the new wires (the leaflet I get with the kit was a) in german, b) so badly printed I couldnt see the numbers 30/36/38? looked the same to me
