You shouldn't need the wire colours for the Optimax Smartcraft guages - they are a "plug and play" item with thier own loom - what exactly are you having trouble with, and do you have photos?

Hi Boab,
The engine installation manual gives more info than the smartcraft sheets/manual.
On the main harness/data cable
The pair of wires BLK/ORN & PNK/BLK are to the fuel tank sender ( disconnect blk/orn if tank is there is an engine battery ground strap connected to tank or sender)
Pair BLK/ORN & LT.BLU/BLK are to oil tank sender
Multi plug with 4 wires TAN/ORN, GRY/BLU, PUR/YEL & BLK/ORN connect to paddle wheel/water temp sensor.( cable are WHIT,YEL,BLU & BLK respectively)
On the speedo harness
There are two pairs of bullet connectors -
TAN/BLU and PURPLE are for external warning (depth ?)horn accessory
WHITE & BLUE are NMEA GPS + & - respectively.
There is also a multi plug which is to connect into the external air temp sensor ( if fitted)
Off the tacho cable -
Is a single TAN/BLU which is for connection to optional visual warning light
and single RED +12v feed (same circuit as engine starting battery)

Unfortunately my scanner is playing up otherwise I would post the schematics here -
Let me know if this helps or if you wish I could use ancient fax technology to send a copy of the manual.

These apply to 2001 model year and above.
Jeff

Boab,
Yes - the d block connector from the tacho does into the junction box - as should the one from the speedo. The cable from the engine also terminates in this junction - which on mine is a four-way, (std I think) with one being blanked off. It doesn't matter which cable goes into which slot on the jctn box. If you are starting from scratch, make sure that the cable from the engine is fitted with the termination resistor at the engine end, not the jct box.
Fantastic instrumentation and functionality. I had a floscan fuel meter from my old set up which was very accurate once calibrated. I kept this but the fuel flow ( l/hr and total ltrs used) as part of the smartcraft is spot on !

225 !!!!!!!! lucky man !

Jeff
