1. Find centre on back bumper and measure hole positions from centre of bumper . My measurements were 20.5cm for each of the middle two sensors from centre mark and 62cm for the two outer sensors from the centre mark. See photos for approximate vertical/horizontal sensor positions. There is plenty of space behind the bumper. However make sure you are above metal plate before drilling holes.
2. All 4 sensor wires were passed through a grommet located on the rear panel on underside of vehicle immediately above the exhaust on drivers side. This grommet enters the wheel well next to location of the wheel jack. Remove the wheel jack to give more access for wiring. Tidy up wiring into a loom using insulating tape and ensure you seal the grommet around the wire both inside and out with leak sealant paste.
3. The earth wire was crimped to a suitably sized spade connector and fitted to the light cluster holding/fixing nut which provides a convenient earth to the vehicle chassis for the CPU.
4. The reverse light feed however has to be provided from the reversing lights which are located in the tailgate for this vehicle. The best way to do this is to locate the reverse light feed wire from inside the loom that leads down inside the headlining inside the vehicle. Carefully remove the three plastic rivets and pull down the rear section of the headlining away from boot rubber sealing strip to reveal on passengers side the loom coming from the tailgate bulbs/wires. Cut into this loom carefully to separate wires and test to find correct wire that produces +12V output when reverse is selected . Note that there are about 8 wires which unfortunately are all black. Most are thinner but at least two are thicker gauge. I found by testing all wires that one of the two thicker black wires produced a switched +12V when reverse was selected on/off. I spliced a suitable length of wire to this wire using the supplied scotch lock and then ran this wire around the headlining and down behind the internal side panels/ rubber sealing strip until I could join it to the CPU.
5. Test system and then tidy up and tape up all loose lengths of wire and tuck CPU and wiring into wheel /panel space immediately in front of wheel jack . Put back headlining and wheel jack.
