Mizz has asked for details of the 1500 O/D loom on Facebook but I have been unable to post the details on the facebook site.

Thanks again Richard. Good detail. Would you have a 1500 parts catalogue number for that harness. I’m curious to see if it’s the same number as the 1850. Overdrive and reverse lamp…UKC4195

I have been unable to find a parts number for that small loom.

UKC4195 is common to both 1500HL and 1850HL. The Sprint has a different part number UKC4624 and I shall probably spend the next hour thinking about why...

To save un-necessary strain on your brain, the Sprint loom is arranged differently circuitry wise and the distances between (and positions of) the reverse light switch, O/D inhibit switch and gearlever are also different. I believe the positions of the 4 wires in the 5 pin plug into the main loom are also different, presumably so you can't fit the wrong one and have it work. Oddly, i've also had this with the auto, where the trans inhibit/reverse light switch loom differs between 1500 and Sprint ONLY in the position of the wires in the 5 pin plug! In this case I don't know which pattern the 1850 auto follows, as i've not had one of those!

Awesome, Thanks everyone. I’m going to order one now from Autosparks for the 1850HL.
