- large white wire black stripe (to other door) (-12v main ground wire)
- large red wire blue stripe (to other door) (PW motor)

- large red wire black stripe (to other door) (PW motor)
- large blue wire white stripe (to other door)

- large blue wire (to other door)
(PDL actuator)
- large blue wire red stripe (to other door) (+12v PW/PDL power)
- small red wire yellow stripe (door lock switch -12v circuit)
- small black wire blue stripe (door unlock switch -12v circuit)

- small blue wire black stripe (not used, originally went to ECM)
- small green wire black stripe (not used, originally went to ECM)
- small grey wire (not used, originally went to ECM)


drivers side small plug:

- small green wire red stripe (to other door)
- small green wire black stripe (to other door)
- small red wire (to other door)
- small blue wire red stripe (+12v mirror power hooks to same power source as large +12v blue wire red stripe)
- small pink wire (speaker wire)
- small purple wire (speaker wire)



passengers side large plug:
- large red wire blue stripe (to other door) (PW motor)

- large red wire black stripe (to other door) (PW motor)
- large blue wire white stripe (to other door)
(PDL actuator)

- large blue wire (to other door)
(PDL actuator)
- large blue wire red stripe (to other door) (+12v PW/PDL power)
- small white wire black stripe (to other door) (-12v main ground wire)
- small red wire yellow stripe (door lock switch -12v circuit)
- small black wire blue stripe (door unlock switch -12v circuit)
- s
mall black wire (not used, originally went to ECM)
- small grey wire (not used, originally went to ECM)
- small purple wire (not used, originally went to ECM)


passengers side small plug:

- small green wire red stripe (to other door)
- small green wire black stripe (to other door)
- small red wire (to other door)
- small navy blue wire
(speaker wire)
- small green wire
(speaker wire)
So I just finished wiring the new harness and relays together. Now I am stuck at deciding where to tap into the power. Should I splice into existing an existing wire, or use a fuse tap. Also, is a new fuse required for these new accessories that I am adding?

Re: 2004 Door Wiring

Did you ever do the DIY thread for the window conversion on the Tacoma. I have a 1995 Tacoma reg cab with the door wiring and panels from a 2001. I started working on this got the mirrors working so far . Do I need relays for the power windows? is there an way to add remote key less?

First off ... The 2004 door wiring diagrams posted earlier in this thread are unlikely to match the wiring for a 2001. Although both model years were within the 2001 - 2004 'generation', the 2001 Tacos carried over some wiring features from the 1998 - 2000 generation for one year only.

Here (attached) are the relevant wiring diagrams for the 2001 model year.

Re: 2004 Door Wiring

Thanks a lot for the info . I think have hooked everything up on the bench, the mirrors and windows work great, but I cannot seem to get the actuators to work. The switches activate the relays and I can feel them click. but I cannot get the locks to lock or unlock. Any Ideas?

I have tested the actuators and they both work

I have ground on the white wires with black stripe

and power going to: large blue wire with red stripe and small blue wire with red stripe.

I am not 100% sure of the year of the donor truck as I bought the parts years ago

Re: 2004 Door Wiring

Does your bench setup simulate ALL the wiring connections shown in the 2001 wiring diagram(s)?

One possible issue is that 2001 - 2004 Tacos' body automation (e.g., the power locks) was controlled by a Body ECU. The Body ECU replaced what was called an Integration Relay in earlier Tacos dating back to 1995.5.

The difference is more than just the name. It might be that something in the 'logic' of your bench setup isn't properly simulating what a 2001 Body ECU would be doing. The Body ECU controls the current flow to the door lock motors / actuators.

Re: 2004 Door Wiring

Hello Enola Gola and Paul Simms,..

Im in the same process of putting power windows on my 99 Tacoma. Its a single cab basic 2wd 2.4 truck. I've gotten doors with wires and the whole wire harness that connects the drivers plugs all the way to the other side of the passengers from a 98 Tacoma extended cab SR5. Ive also grabbed the fuse box from under the dash ( came with a light blue box). just wanted to know that I'm only interested to install the power windows nothing els. The controls from the door also has the power door locks buttons. Im planning to use the after market keyless entry to use on them.

Enola - what is The Body ECU control? what does it look like and where is it located?

If I'm thread jacking I do apologize .. just new here and need help.

Thanks in advance

I'm not sure why you're asking, because ...

You don't have one on your '99, and there wasn't one on the '98 either ...

From 1995.5 through 2000 certain control functions were handled by an Integration Relay unit located in Junction Block No. 1 (the fuse box unit behind the lower left dash).

In 2001 the Integration Relay was replaced by a Body ECU unit located in the same place (lower portion of J/B No. 1).

I've never seen any tech documentation explaining the difference(s) between these two control units. My theory is that the Integration Relay was not digital or not as digital as the later Body ECU.

Re: 2004 Door Wiring

Here (attached) are the 1998 and 1999 power window circuit diagrams.

They appear to be identical (but I didn't check every last detail ... ).

Re: 2004 Door Wiring

In response to a PM ...

Here (attached) is an illustration of J/B no 1 from the '99 FSM. The Integration Relay is embedded within the junction block unit. The illustration shows the location of the exposed Integration Relay connector.

The connector pins are numbered from 1 through 12 reading right to left.

This is the same relative location, connector location, and pin configuration as used in '98.
