AS wiring questions...

[Corsair613]

Having succeeded (barely) in passing all of the AS wiring loom's connectors through both holes in the right-side luggage bin, I set to pre-positioning its forward branches. A few questions have arisen:

- Exactly how do the AS loom's Speedo and Tacho wires (one each) mate up to the Ultima loom's connectors and gauges? I have the standard analog dials. Neither set of "instructions" (Ultima or AS) is at all clear on this.
- What function is served by the AS Check engine light & Ignition switch ON position wires and where do they connect?
- How do the four connectors intended for the battery's + terminal (two each from the Ultima and AS looms) fit on that little post? Is an extender necessary and available?

On the bright side, I got the underside of the center section painted black yesterday (the red really pops now!) and installed the wiper motor.

The check engine light is best not connected - blank this off. Reason being that the state of tune will trigger some error codes and mean the light is always on (at least that is what Gail at AS told me on my LS7). I have connected it up to a light (fortunately I fitted it under the dashboard on the heater control unit plate so it isn't directly visible) and sure enough it is permanently lit. I have checked engine error codes and always get system lean warnings which are the ones Gail said to expect due to it running a little lean at idle.

I haven't got around to removing it yet.

Hi Mark,

Thanks, I'll tie off the Check Engine Light wire. Any thoughts on the Ignition Switch ON and speedo/tacho wires?

I can't remember all of it from my build 2 years ago, one day I will regret not making better notes!

But yes you will have 3 connectors all onto the battery terminal. This is OK but you wouldn't want to add any more!

The speedo and tacho fittings were something I had to check with the factory - I can't find their reply. I remember it was not obvious though, but when connected it all works. I too have standard gauges. Sorry I can't answer that one.

Mark,

Thanks - much appreciated!

I think I've actually got 4 connectors vying for my battery terminal. Two from the Ultima loom and two from the AS loom. I was planning to leave a trickle charger pigtail in place, too. Looks like I'll need a terminal extender of some sort.

I'll write Richard for the speedo/tacho wiring details.

I have the starter cable and one other at the battery.
The 'other' cable goes to a 100A fuse mounted on the chassis rail inside the passenger footwell. All other power cables come off that fuse.

Interesting. Was this configuration suggested by Ultima and/or AS or did you opt for it on your own? Definitely food for thought.

I have seen this in a couple of builds. The first time I saw the big fuse concept, Uwe (Spatz) had them in both his Can-Am's. I have it scheduled in my build and others too.

All my own work but primarily driven by wanting to tidy the battery terminal rather than a need to fuse the supplies.

I fitted a distribution block.

Two wires to battery +
One to starter and the other to the block.

Everything else is fed from the block with 4 terminals. No fuse in my case but less clutter on the battery.
