DIY JDM style side mirrors combo lights (Signal+Parking+Courtesy lights)

Sorry, my bad. It's fixed. I also included a link to finding the L7 connector.

 

Not sure what I just walked into. Was refering to the pdf attachment with the wiring diagram. Was this deleted to?

 

Got it, thanks.

 

Sorry, I misread the diagram. It's A is U3 and B is U13....

I am fixing it....

 

Ok, according to Jayvee (Thanks!) in another thread, connector 2A (we want pin 52) is located on the instrument panel junction block near the main ECU and junction connector UL1 (we want pin 8) is located on the left side of the dash. Form UL1, the wires run up to the roof, where U3 and U13 are located.

I wish I knew how to search with short strings (like "2A")

Hope that helps...

 

Yes, the positive side goes to battery and the negative side goes to the blue CTY wire.

If you find the 2A connector, the red wire at pin 49 should be the 12V dome light supply from the dome fuse. It connects up with the red (or red painted) wire to the positive side to the under-door puddle light, which is where I plan on tapping for it.

If you dig around, I think you should see a blue wire running up the driver-side A pillar. If there is only one, then that should be it. If there are more, you want the one that goes to ground when a door is opened.

 

Actually, you might be able to find the blue CTY wire on the 3B connector (under the dash?) more easily by following the wiring back from the under-door puddle light. Look for a large square connector with 96 pins in a 12x8 array (there is another connector ( 4B that looks the same). If you follow the hot wire from the puddle light, it will lead you to 3B after going through a junction connector. From the driver's side, it will connect to pin 48 (it will be on the outside edge of the 4th row (once you've oriented your view)). Once you find 3B, there should be a blue wire at both pins 18 and 78. You should be able to tap into either one of them.

Good luck.

 

It looks like that should be the OL1 junction connector, and there should be a similarly wired junction connector (NL1) on the passengers side. That's the right red wire that we can use for the hot side of the mirror welcome light. Do not use the yellow wire, it is the return from the door puddle light and uses a different grounding circuit.

When you follow that red wire back under the dash, you should find the large 3B connector. It probably has a big bundle of wires connected to it. If you can't get to it, you can try finding the UL1 junction connector or the 2A connector to the Main ECU. The UL1 should be a nice-sized gray 18 pin (19x2) connector. Since it's heading to the roof though, I fear it may be up high into the dash. The 2A connector is an elongated 56 pin white connector divided into 3 sections along its length. Along one edge are a series of fat wires, 6 in each of the two outer sections and 2 in the middle section.

I will try to organize more information and include connector drawings in the morning and post them.

 

I am attaching a file that shows the wires and connectors that should work for wiring the welcome light. Let me know if I mislabeled anything.

While you could use any constant-on wire, I prefer one from the dome fuse. Fortunately, such a power wire is right at the doors leading to the puddle light, so it should be pretty easy to tap into. Just follow CivicSky's instructions borrowed from the door sill install and tap it to the positive side of the welcome light.

There are a number of potential places to find the blue wire to the courtesy ground circuit to tap into for the negative side of the welcome light. To help, I have included the connectors with the pins color-coded for the red hot wires and the blue courtesy ground wires. Except for U3/U13, I believe the connectors should all be around the driver's side footwell or left side of the dash so that means that you will need to snake the passenger-side wire under the dash. Hopefully CivicSky will be able to find the most accessible place to tap.

 

Dang it... I really wished I paid more attention in my HS electronics course.... Those diagrams are all Latin to me.

 

If you pop off the overhead panels, I'm sure you will see it. That wire bundle seems to carry all the wires needed up there.

So you gave up looking down below? The 2A connector should be findable because there are a lot of other connectors that also plug into that ECU, such as L7 and L8. I haven't seen a clear picture of it, but the attached diagram (from http://priuschat.com/forums/gen-iii...elp-finding-l7-connector-auto-headlights.html) shows where L7 and L8 are located (panel to the left of the steering column). In the diagram, I think the purple wire bundle is what leads from UL1 to the roof but it's not labeled....

 

I found a thread discussing the A pillar and tweeter removal that may help our quest. See post #32 of http://priuschat.com/forums/gen-iii...tronics/68491-front-dash-tweeter-removal.html and look at the second image. That black bundle you see on the left should be carrying our blue wire and it looks like you can access the UL1 connector (or at least the wires) through the tweeter opening. And apparently the parts just snap off. I assume we can slip a wire down below. If someone doesn't get a chance to look, I'll see if I can give it a try later this week.

 

I gave up and posted a new thread asking for the 2A connector's location in the Electronics forum. I know, it's not as much fun that way.

 

Thanks for tearing your car apart -- again!!! And good luck, hopefully that is a connector next to the tweeter that you can just pop off. My dash doesn't rattle (yet) so I feel it would be better to remove as few panels as possible, so as not to tempt anything.

I remember that I have one of those fiber optic inspection cameras that might just come in handy if the connector is buried somewhere.

 

Danny, Deleting my third post again with no links or giving away information as to where these signals can be purchased at a great price only proved to over 20+ members chatting away on Google Groups and e-mail about what is really going on here!

Again, why don't you charge Nigel a vendor fee rather then asking a $20 commission price on each sale and let members purchase these signals at what most thought was a fair price from Nigel-JDM NOW! His shop is known on Lexus Forums as a very reputable vendor/shop.
