i think its worth it if you are absolutely positively sure you can't handle the task, and want to wait a good few months for it to be done.

it's up to u... i've been waiting quite a long time for mine from them... they've had it for many many months before they even started..... it's not their fault cuz i'm sure they're busy... but ya... I'm not here to bring anyone's name down because Mckinney's customer service is pretty good, they return emails within a day or two and I'm assuming they have a good reason for take this long on my wires... but yeah... if you want, go for it, but think about it before you jump into that and possibly grow white hair

Atleast try it before you pay someone to do it.

If you try it jsut label them first before hacking into it. Easier for the next person to figure out in case you fail.

I did my own wiring and it worked. My very first wiring job. My very first with everything, really.

mckinney does a 100% professional job and are will without a dobut give you a good harness.

its expensive but if you dont know a soldering iron from a butt connector dont touch the harness.

if you do know how to read a diagram, and solder, do it yourself. its pretty straightforward.

I had mine from them in a couple of weeks, but that was back before the swaps really started taking off. They did a great job, and seeing all the wiring issues people have had, I am glad I went that route.

Remember that it doesn't solve all your issues. your speedo and tach will still be wrong, although I think they can fix that for you if you send your cluster. You have to deal with the lower harness yourself, but it is just plugging things in, so it is easy enough to figure out.

You send the upper KA and the upper RB. You then use the lower KA harness and connect it to your RB transmission if I remember corectly.

What do you need to send the KA upper for? All I did with mine was hack it for a few wires that I needed to extend and I used the shield tubing from it.

When you get the rb harness back from a shop, I figured the wires would be labeled. Then do you have to wire it to the KA dash brown and white plug? That is pretty much where all the connecting happened. I thought you might have to send a portion of the KA dash wires to a shop so you can just plug and play when you get it back. And also what about the fuse box wires that you would tap into. I thought a shop would do that also. But I guess you have to do that also? Am I just not understanding it right?

Its cool...no worries....

You use some of the plugs off the KA upper harness to make the install clean and tidy....and also so its easier to remove everything.

I like to get the KA upper & lower & the RB upper & lower...Just handle the whole thing.

There is a little work that needs to be done to the KA lower harness to make it completely compatable with the RB motor.

Anyone wanting to attempt wiring it themselves can contact me and I will be more than happy to walk you through it.

Anyone wanting it just plain done, get ahold of me and we can work something out.

Do it yourself. I don't know hardly anything about wiring and it only took me a couple of hours. I have a bunch of links to threads that are relevant to the wiring process.

Spend the $350 on some performance parts. :)

I did it myself, but I was just trying to understand what actually gets done when you pay for it.

Some of the harness are taking longer here The R34 we are working on getting the factory manuals from Japan and getting the wiring translated before to gets sent here takes time. the rest depends on how many I have to do when your harness get here and our work/ race schedule with the exception of the R34 harness usually take 2-4 weeks because I usuall have 20+ harness(RB/SR) in house to do at any time..

will your wiring harness enable the obd connector, check engine light, ka speed sensor? dose it basically make it how it would be if nissan offered the motor with the car?

Just wondering, Nismo_rb says you just plug the ka lower in the rb transmission, but jon says theres a few things to do to the ka lower harness. Who's right? and if you have to modify the ka lower, what do you have to do?

Add the wiring from the RB lower harness for the knock sensors and swap the oil sending unit plugs....On S14 you need to extend teh starter wiring also(for some unknown reason)

Jon is right. I haven't done it a while, and forgot about those other connectors.

It's understandable, are you guys actually getting those mailed here or faxed here? Also, will the speedometer and tach and the engine temp work correctly (accurately) after you guys do the R34 wires?

our wiring we hook up the Nissan consult plug, the OBD2 plug will not work as the computer is not compatable, the wiring is done to make the gauges work, but the tack and speeedo must be modified to tread the RB 6 cyl.....and speedo recalibrated. after the manuals are transulated mailed to me.. WE "recomond" that you use aftermarket direct reading water temp and oil pressure gauges as this are important to the life of your engine!!!!!! Mack

Hey Mack, Why wait for the manuals to be translated from japanese?Couldn't you get a copy from Australia, New Zeland, or England?At leeast it's in English evan though you would still have to translate all the "Metric crap".

They do not have the R34 YET and MOST of there's are incomplete on the wiring..Even though we do alot of harness their only a small part of our work load for a month. I am sorry it takes so long some times but we try to give everyone the same attention to detail it deservise and not just pump them opur to get the $$$$$$ Everyone for free to use others or try it them selves. We do our best but there only so much we can work and that is about 80 hour a week...
