How to add SKS to the hatch and passenger door on a 1 door SKS Gen III Prius

yeah i ended up pulling back the bumper like you did. it was actually pretty difficult to pull out the bumper and required more force than i thought. even then, once the 2 clips of the bumper were out, my wrists were totally getting scraped by the bumper/dirt/etc that was down there.

then there was the part of getting the 2 bolts from toyota on. i got the two you mentioned in the document, but they cannot be turned by finger. my bolts must have been painted over from the factory because after about 2 threads it stopped turning and i had to use some open ended 10mm wrenches. i was lucky enough to have a mini ratchet that would fit in the space, but it is pretty difficult.

if i had to do this mod over again, i could shave off 2 hours. i think it can be done in about 4 hours by yourself, or 2 if you have someone helping you that can pop panels and work on the headliner/rear bumper while someone works on the front doors

 

I would LOVE to have this on the hatch. Not worried about the passenger door (I'm single!), but the hatch would be REALLY nice. Unfortunately, this looks to be a little more of a project than I really want to undertake at this point. Especially the running of all the wire, the taps, etc.

Anyone closer up this way try this yet? Would be willing to pay a little $$ for install, but don't want to end up paying a separate place like $400+ to do this.

Hmmm, I might be taking a cruise out of Port Canaveral later this year. Maybe I'll drive down and pay Brett to do this for me

 

i am wondering if there is still a way to increase signal reception. i am not good with electronic circuitry, but maybe someone like pEEf knows if there is.

 

Yes, this could be done, but it would not be an easy thing to implement, as it would require the addition of non-trivial circuitry.

The cheapest/easiest would be to buy the 3-door SKS ECU.

 

Both!

Adding a 4th would balance the power so all antennas had the same power, but it's still going to be less.

The only other way would be to modify the SKS ECU to put out more power which is non-trivial.

 

Hello. And thanks to all of you that made this mod possible, especially BrettS.

Came with a pair of questions:

I'm on the verge of order the parts.

I'm only interested in the SKS for passenger door. Not for the hatch.

So the parts i should order are:

1) SKS enabled front door handle. 144.77$. (of course the same color part for my car color).

2) Wiring harness for passenger door SKS handle. 37.55$.

And anything else.

Am i right?



Another question:

Since i won't install the SKS for rear hatch, i only need to tie the following wires:

Pin 6, White wire with two black dots to the certification ECU Pin 18, black wire.

Pin 7, White wire with two yellow dots to the certification ECU Pin 20, yellow wire.

Pin 8, White wire with two red dots to the certification ECU Pin 4, red wire.

Pin 20, White wire with two blue dots to the certification ECU Pin 32, light blue wire.

Pin 21, White wire with two green dots to the certification ECU Pin 3, green wire.


Is that correct?


I think it is correct, but would like you to confirm before i cut the wires of the ECU.
Regards.

 

Something like this?

I think you used that connector to tie the wires:


but i don't have it.

I only have something like this:


Then i think i should cut all the ECU wires except the green one, like this:



One last question:
Did you disconect the battery for doing the job, or it is not necessary?

Regards.

 

I went to buy the tapwires, so hope don't need to cut the ECU wires, except the red one:

 

Hello. I can confirm the above code for the red one:




Hope to begin installation soon.

 

Do you think the front and rear door handles are the same? I wonder if you can have 5 door SKS...

 

Just installed my SKS for passenger door only, following Bretts tutorial.

Everything works PERFECT. So thanks again Bretts and others for your investigation.

I did not notice any drop in detection range. And did not notice any drop in working response.

Now some pics and advices.

Both handles:



My wires coming from door are not white with dots, are colored. Luckily the pin number still match with the tutorial ones.



Some tapewires didn't work properly due to reduced room for making good connections. When i connected by the first time the open and close sensor didn't work. So i had to cut that ecu wires instead of use tapewires for all connections.



I made a mistake during the installing of wire harness:

Once i put the new handle in place i went too fast and the first thing i did was to plug the harness to the handle.



Well. After did it, i found that drive the harness around the rail window was IMPOSSIBLE. The harness is reinforced with rigid plastic.

So i came to the conclusion i had to remove the harness...but now i was unable to take it out from the handle! I didn't know how to do it.

I tried to remove the handle...but now with the harness pluged to it...the handle didn't come out!

It were panic moments.

Finally i found the way to remove the harness from the handle. The black plastic part must be removed first at all. I was at the verge of broke the harness because i didn't know how to remove it.




So know it: you must not plug the harness to the handle until the harness be in place.

But at the end everything went ok, and i very happy with the mod.

Thanks again.

 

i had some panic moments with the handle also. i was trying to make the harness fit into the grooves that were already in place. i eventuall got it in but after an hour of cursing, and removing all the trim pieces of the handle itself. in the end it wasnt worth the trouble, but the trouble, but the mod itself was totally worth it
