Hi Everyone
We have an abundance of the S14 SR20 to s13 engine harnesses so we are looking to do a group buy.

Wiring Specialties S14 SR20DET Into S13 240sx Engine Swap Harness

Regular price is $399 but if we can get 10 buyers, the harness will cost only $300.

Leave your name is you are interested! We look forward to chatting with you guys and posting up some more of our harnesses in the future.

oh hey been meaning to get in touch with you all. I just did an s14 vtc sr swap in my friends s14. we used your complete upper and lower harness. Loved it. made the sr swap a breeze as far as wiring, and used the lower with the auto to 5speed wiring. again saved so much time.

I would def use it again, Which I just so happen to be getting into. I picked up another S14 vtc sr with you s14sr to s13jdm body wiring. although i am not sure if it is pulg and play with a usdm body wiring harness. If you could PM me with any ifno it would be great!

People should jump on this IMO

Sounds great! Glad to hear things are working out well with the wiring.
Regarding your new project. Whats the application now? S14 SR into S13 car? If so, then the harness should work. Look for a part number wrs-s1413-main.

Hope this helps.

Wondering if you can do a b14 sr harness into a s14 with sr?

compact - but why?

My buddy has an sr in his s14 and wants to use a b14 jwt tuned for his setup and wired with the b14 harness to utilize the obd2 system.

Come to think of it, anyone with a sr powered s14 would probably love to be able to use the obd2 from a sentra. It would definately save a lot of people some hassle.

Not a bad idea, but off the top of my head, i am not sure if a distributor based ignition ECu can run direct fire.
It would be the first issue i would tackle.

I was already thinking of that. Jwt would have to solve that problem or just run a distributor.

Direct fire is so sexy though....
I think the OBD2 issue will come up again soon... We'll have to tackle it somehow.

I know! We would hate to loose the cop but the obd2 issue is a big deal for alot of people but most just jump on the forums and say ” can it be done” everyone says no and that is that. I have an s13 w/ sr and a b14 sr20de-t and I don't see anything being all that big of an issue. If you decide to do a harness you would put it in the tech section. I'm sure you will get a lot of hits.

Wow, I'm surprised no one took advantage of the initial group buy.

Times are rough, and someone always has a friend that "knows how to wire a car" This, of course, works out 1 out of 50 times...

^ so true. When I was a rookie I wired up all my own stuff. As my skills and knowledge advanced I have found a lot of my own mistakes and have had to double back on my work..... And this s13 sr to s13. I've don't quite a few s14 and s13 wire jobs but for someone that doesn't know the ins and outs of these wires will definately get it wrong. (not to mention how clean are you really gonna get it)
Hey pyro, you find those bungs we were talking about? ive searched but can't find anything.

Thanks for the response Yury. The pervious applacation was a S14 SR20DET(WC ecu) in a rhd swaped s13 hatch with jdm Chassis harness. I am installing the S14 SR20DET(WC ecu) in my LHD hacth with a 91 five speed chassis harness. The plug that goes into the body harrness from the engine harness is white an extra wire with a completly different pin out than the brown plug. The shapes of the brown and white plug are the same and both are the male conetors. I have the female brown plug that i can splice into those wires but I have no idea which goes where since your harness seems to have different color wires going into the plug compaired to the wires coming from the ecu to the point it is wraped in tape. Any help you can give would be great. if you would like to email me just add @hotmail.com to my screen name.

WE have put our S14 SR to S13 harness back on sale!
