So you bypassed the relay altogether and fed the 5 amps directly through the Nissan switch? And it can handle that current? The kit switches looked like they could only handle a small current. Also, you mentioned buying a Nissan wiring harness. The rest of us will need to solder the wires directly to the switch, no?

The relay is not used to keep current out of the switch, it's used for series/parallel switching. Nissan figured out how to do it with a specially made switch. If you look at how it's wired, you will see that heater current is indeed passing through the switch. (Another reason to get rid of it!)

I think the female mini-spade connectors will fit this switch without too much trouble.

You should have seen the rev 1 schematic I made on the back of a piece of masking tape. I re-drafted it (at great expense) just for MNL! =)

Sometimes a pencil and paper trump the PC.

Oh, the sacrifices you make for your fellow LEAFers, Phil!
Thanks for posting on the mini-spade lugs. That will save a lot of hassle. I did take an ohmmeter to the Nissan switches when they arrived and found continuity to be consistent with your schematic. You just saved me from having to do same for the kit switches ;)

It looks like there are a number of us in the Bay Area that want to do this job. I won't get to it until the period between the holidays, I think. But Electric4Me has volunteered to teach us all how to do it. Is anyone game for the week after Christmas?

I'd be happy to help as well, but I'm OOT until after new-years.

I received my heaters, the "instructions" say is it is the Roadwire RW-SH1518B Seat Heater. I bought the front/back kit. There are 4 identical units that arrived. So if two people want to do front only they can save a few bucks by splitting an order.

I've also ordered the OEM switches for the front seats.

I think I have a crimping tool should handle the mini spade connectors that Phil suggested for the OEM switches.

Sounds like a party to me--at least 4 people want to do it now. Maybe we should have an SF BayLEAFs special event? :lol:

I'm about to order a 100 of the 0.110 female spade connectors:

Each OEM switch requires 6 so each car would require 12

so I can be ready to party :)

Probably need to come up with a full parts list. I guessing we need some taps to tap into the lighting circuit and the adapter to pull power from the fuse block.

I'm in. I have the heaters and switches. Just let me know when and where.
