Converting from SR/SR5 non-LED headlights to 2020 full LED headlights

If I had an SR or SR5, and money for the LED headlamps, I'd just snip all connectors and crimp the MX150 connector and terminals. Then I'd assemble the opposite harness, one going to the original headlamps, since I'd have all the required connectors. I don't think I'd replace the LED with another set if they get damaged by a shopping cart at the mall.

Hmmm.....can you explain this a little more clearly?
We appreciate all your time and expertise with this.....

This is what the non-LED headlamps looks like:

I'd remove (de-pin) all terminals from the connectors. Snip the power side wire on Headlights, turn signal. These would get an MX150L female terminal crimp and insert in the MX150 female connector.
The marker's connector would not be altered and only covered by a "plugging" connectors.
The only ground wire snipped and terminated with a MX150L female terminal would be the LOW Beam ground. All other grounds would keep their OEM terminals. The HIGH beam ground would need to be bundled, covered and affixed to prevent damaged.

For the DRL I'd duplicate somewhat the same feature the higher end model uses. IGN fuse to 5 pin relay. coil tapped into an add a fuse from the LOW beam to turn DRL off. DRL would be ON at IGN. (no control to ON or OFF switch/app)

For SR without DRL app control, the rear turn signals would need to the tapped and the rear bulbs would need to be changed to LED's and the FRONT turn signal would need a resistor.

Excellent !! This is something I may go for now - I like this much better - appreciate your efforts!

Pink is the terminal that would need to be left OEM, covered and tied down.
This is for an SR.
Resistor to FRONT turn signal, REAR turn signal tap, rear turn signal to LED lamp change. Look at post #61.
The Parking/Tail wire on the turn signal connector would be removed, snipped and terminated with a female MX150L terminal. A rubber plug for the empty slot on connectors.

Is there really a months long waiting list? Even if there is, that doesn’t necessarily mean there’s a lot of demand since months long waiting list isn’t a number. If plenty off people have already made the jump and there was enough demand, a harness would have already been manufactured by a third party.
The OP wanted OEM and had $1500 to spend on them. I don’t believe the majority of Tacoma owners are in the same boat. You can retrofit for less than half the price or get the Morimoto or Alpha Rex for $400 less, I think the majority are going that route.
I could be completely wrong and maybe the majority of Tacoma owners want to spend $1500 on OEM headlights. As an SR5 owner, I’m looking at headlight options, but OEM are not even on my list of options.

You should make this harness and make some money for the work involved.

Getting these items would get the LED headlamps connected after a few snips.
Edit: it's MX150...(33472-0601) the MX150L will not fit.

Pic owner is @Lt. Dangle

This is a view of all connectors removed without cutting the terminals, and various other items removed.

Detail on side marker connectors

Can be used to trigger an added circuit (parking/tail) via a relay or other creative add on.

OP, or anyone with an SR/SR5, I need a view (pic) of the Turn/DRL bulb holder (with bulb) connector of the headlamp from an SR/SR5, and the slot pattern where it attaches on the headlamp. TIA

Do any of these help ???

Thank you @bizjettech
I'm looking for the same but for the Turn/DRL on an SR/SR5 with incandescent bulb.

Sorry, my mistake.....here you go.....

caribe makaira · Jul 14, 2020

Thank you @bizjettech.
Would you take a pic without bulb so the locking tabs are visible?

Do you see a part # on the bulb holder?
