Hi, I have mspnp and I'm looking to purchase an LC1 tomorrow. Just wondering where/how people have wired them up. Where can I snag a switched 12v power supply from and where did you mount the lambda cable box?

Read the manual front to back then re ask. I'm sure it's in there.

i used the diagnostic port for timming lights etc. And mount the sucker where ever you can fit it.

Sensor comes in from under the shift boot.

LC-1 sitting behind the center console.

Power off the ECU, Plenty of switched 12v to tap off: WHT/RED wire PIN 1B

that is if you use a bung other than the stockish port location.

could you be any less help? what manual are you talking about? the lc1 manual? read it... believe it or not, it doesn't have anything about mounting it in a miata.

Thanks to the others that responded, think I will try to get the module installed inside the car. Does the diagnostic port have 12v? I didn't really investigate thoroughly, instead when timing my car, I just stole 12v from the car next to me

the little blue connector plug near the driver headlight is a 12v source. (for a timing light so you dont have to steal power )

I was referring to the PnPs manual and I could have probably been less help.
Just make sure you use one of the ECU grounds for the LC1. For the least amount of interference and problems it is best to use the same grounding spot for the MS and the LC1 controller. Which means you should tap one of the ECU wires seeing how the PnP has the grounds pre-determined.
That is just a common thing with MS. Wise to do the same thing with the 12v but not necessary. Maybe you don't have to for some crazy reason with the PnP.

There are plenty of places to grab switched +12V either from the fuse block over the driver's kick panel, or from the underhood fuse block.

I think it was Jerry @ DIY-A who suggested not stealing power from the ECU harness. I didn't throw a DMM on it or anything, but the sensor heater probably takes a good bit of power.

Easiest thing to do is to pick up an add-a-circuit for $5 at the parts store, plug it in at the interior fuse block, and bring the wire over to the controller. That way if the LC has a short, it doesn't blow the fuse in front of the ECU.

I don't think Chad was being a dick. For real yo, everything you need to know can be found on this forum if you use the handy dandy search button and the LC user manual, which is a free d/l from innovate.

I recommend picking up the LC from DIY-Autotune. Their support is world class when/if you have a failure. Jerry went way out of his way to help me out when I was having a problem.
