There aren't many pictures to this one as they don't really do it justice - in the flesh it looks good and I am confident all the pin outs are correct. I've tested every single one of them (several times!) and its now fitted to the car. The thing is its completely hidden away now, which is great and I have achieved what I wanted, the bad thing is no one will ever know the effort that went into it!
Some notes:
- Those of you with a keen eye will notice the Spartan2 wide band lamda controller on the left. After researching wide band, narrow band, closed and open loop systems I went with this (https://www.14point7.com/products/spartan-lambda-controller-2). Its a no brainer really, it make sense to go wide band and this is the best value\rated kit available.
- I'll cut the earth wire down to length and terminate it when the ECU is fitted, the earth point is already in place so required length is unknown.
- I'm waiting on a connector for the oil pressure switch, it was difficult to find but managed to find one available on eBay, should be here next week.
- The other connector I need is for the oil pressure clocks - that will come with the clocks when I purchase them. Still undecided if I should go down the smiths gauge route or go digital (digital is appealing most)
- Every single connection has been soldered, heat shrunk and tested - I took my time with each of them and made sure they were all 100%.
- Every pin has been tested for continuity, the wire gauge was defined by emerald in their fly lead.
- I used a combination of resources to map the various ECU pin outs and GBS engine loom pinouts. GBS were helpful on their forum when I asked for a pin out list for the engine harness, what I had already researched matched what I was told which is always a good sign
- The emerald documentation is great with detailed information including examples
- All of the connectors and sensors are available direct from emerald
- The Ford wiring diagram I have was very helpful, especially working out sensor pins
Its now in the car, done. Its been a mission and I am now one step closer to turning they key....
Pinouts are as below - please feel free to use these for reference but of course do *not* take them as gospel, check your own and do your own reasearch!
