More Wiring…plus Windscreen back on.

There are lots of wires inside the cabin area on the Canems loom and the AK loom that need connecting and this was definitely the job I was least looking forward to. I started off by connecting the ones that were familiar to me, either from looking at the manual, or from watching Russ Howell’s videos.. 

Reverse light switch - I had already run a reverse light switch wire up and through in to the cabin so I just needed to connect the two black/white wires from the AK loom. I soldered the wires and covered with heat shrink before placing them back in the conduit.

Heater motor - A plastic connector had been supplied with the Heat 3 heater purchased from Car Builder Solutions. There is one wire, black/yellow that is not used as the Heat 3 model doesn’t have the dual speed option. The remaining wires connect as follows - blue/yellow goes to orange, and brown goes to black.

Windscreen on - Whilst I was waiting for Canems to get back to me in respect of some wiring queries I thought I might as well re-drill the holes for the windscreen centre stay and fit the windscreen escutcheons and windscreen. I realised the windscreen wiper motor was going to be in the way of one of the bolts securing the windscreen. Luckily I was able to loosen it enough to enable me to get the bolt in place, I certainly didn't want to take the wiper motor and rod etc off again! 

SMS Autospray inadvertently filled the holes for the windscreen centre stay as they thought these were not required, I therefore had to fit the windscreen, then remark and drill the holes before fitting the windscreen in place. I made sure the centre stay was tight as it's not easy tightening this when the windscreen is in place. I made some rubber gaskets for the windscreen escutcheons out of an old bike inner tube. These seem to have worked really well and they definitely stopped the escutcheons from digging in/marking the paintwork..

So I received some further guidance on the wiring from Dave at Canems and Neil at AK and was now  I now ready to tackle the wiring from the Canems relays. I will list out below what I have done so far and where the remaining wires need to connect to:- 

Fuel Pump - The fuel pump positive (my red wire) needs to run to one of the Canems relays, the relays have numbers on them and this one needs to go in to No 87 (Canems supply a spade connector for this). The fuel pump negative (my black wire) needs to run to an earth. I made up a bracket for this on the chassis centre stay remembering to scrape off all of the coating to ensure there's a really good earth point. I used the same connector to attach another earth wire for the USB (my brown wire).

There is another wire that needs adding to the Canems relay (No 30) which I think is also for the fuel pump (Canems supply a spade connector for this one as well). This needs to connect to a 12v permanent supply on the AK loom. Canems suggest this runs via a 20amp fuse so I will be swapping out the 10amp fuse  once I've worked out which fuse this applies to. Neil at AK has suggested that if the other spare 12v perm supply runs to the same source then it will probably be best not to use this one as well, just keep it for the Canems relay (No30). 

I have now connected up the new wire coming from the Canems relay (No30) to the 12v permanent supply. As mentioned above I just need to check which fuse this is using on the AK relays and change it to 20amp fuse.

Red wire from Canems Relay - I have also connected the thin red wire coming from the Canems relay that needs to go to the ignition switched 12v supply on the AK loom. To keep it all neat and tidy I ran this in the same conduit as the new wires to the canems relay (No 87 and No 30 that are mentioned above). I have spliced the switched 12v supply so I can also use this to provide power to the USB. All connectors have been soldered, heat shrink added and placed in conduit. It's about as neat as I could get it.

There are a number of other loose wires from the Canems loom. The White wire is required for the rev counter, the Brown wire is required for the oil pressure warning lamp (this then goes on to ignition switched 12v supply). I have put these to one side at present and will be connecting these up when I start work on the instruments.

Green Wire from Canems loom - The green wire from the Canems loom needs to replace the black wire on one of the AK relays, this is for the fan. I snipped off the black wire and added heat shrink and tucked it away. I then connected the green wire (85 on canems relay) to the remaining black wire (86 on the AK relay), used a solder sealwire connector before running it inside conduit.

  

Wires not required - For info the following wires from the Canems loom are not required: Blue (charge warning lamp), Orange (secondary maps), Purple (optional input for aftermarket sequential gearbox modules), Black (aftermarket EPAS modules)

Re above, the blue wire (charge warning lamp) is used from Canems loom in place of the one from the AK loom

Wires for USB - I now have the power and earth wires ready to connect the USB (see above notes for more info)

Next is to make up an extension to the wiring so I can connect the two ends marked in the photo below, I ordered some extra connectors from polevolt rather than cutting these ones off. 

I also need to extend the wires for the accelerator (wires in the photo without conduit) as they are nowhere near long enough..

7th July - I have now extended the required wiring as per the above photo, I seemed to be able use the connectors from polevolt fine for this however using them for the wiring from the accelerator was particularly frustrating, it just took me a long time and I couldn't get the crimper to work very well on the connectors! I gave up in the end and decided to use spade connectors on each connection, soldering and placing heat shrink round each individual one. I then placed all of the wires/connectors in conduit. Thankfully all now done and tidied up. Hopefully I never have to get to these again!!

I am glad to get this part of the wiring out of the way.. Hopefully the above all makes sense and I haven't repeated myself too much as I've been adding to this blog thread over a number of days!!
