I want to build an engine harness from ecu to my engine for both my Twincharge Civic and 3-stage vtec CRX.

I was looking at http://www.hondapartswholesaledirect.com/parts-catalog/honda/civic/1992/3dr-si/kl5mt/engine/engine-sub-cord-clamp

@ a cost of $371.36.

Then I was looking at Rywire
http://www.rywire.com/catalog/milspec-tucked-dseries-harness-p-49.html
But $599 starting is freaking nuts.

Looked Chasebay.com
http://www.chasebays.com/product-option/acura-integra--honda-civic/chase-bays-products/chase-bays-engine-harness--hondaacura-b--d--h-series
Start $549 and they have a shitty reputation on D-series.org  http://www.d-series.org/forums/engine-management/164301-rywire-vs-chasebays.html

Looked at http://www.d-series.org/forums/sale/149754-fs-new-civic-tucked-engine-harness.html his work works good and has a good rep. but I can buy an OEM harness for $100 less.

He has a good write-up and doing your own which looks easy.

Also looked at http://wire-worx.com/headlight-harness/22-wireworx-honda-civic-eg-wiretuck-in-a-box.html
$399 starting out, with lots of customization options.

I was given a link by JD, http://www.bmotorsports.com/shop/index.php/cPath/109_110
But I need some help figuring which pins and connectors I need.

I have the Sumitomo catalogs on pdf and printed, but the p/n do not match bmotorsports.com p/n.

So does anyone have a spreadsheet on the p/n and or sources for pins and connectors, I want to do this as a new harness.

I can get different gauge stranded wire I want and I can have 3 or 4 harness to play with to match up lengths and such.

I already have diagrams on where all the connections go, I just need some good p/n's.

there is a thread in Hondatech with a lot of info about this..try find that....

Tried finding a link, all I could find was the p/n to a box of variety of different pins from the dealer for $300.

Russ i would just try to find a bunch of factory harneses i imagine the 3 stage vtec harness coimpared to say an ex is 2 more wires? i could be wrong but just de loom and re loom away honda wiring as far as actual wire is decent quality its not as awesome as german wire in the last 10 years but good none the less

Yeah but I need new pins and connectors, and if I get the hang doing mine maybe I could make some to sell. 

[PhilStubbs]

I can't add a lot to this thread except, DO NOT BUY A CHASEBAYS HARNESS and wireworx would be the place to get one if you decide to buy a premade harness.

I have first hand experience that the chasebays harness is complete garbage. Luckily it wasn't my car or my money though. Also, a good friend got a free harness from him as a sponsorship and promptly sold it after lots of issues before getting it and after getting it. He is now a wireworx dealer and has nothing but good things to say. This guy shaves and tucks 3+ bays a month.

[92CXyD]

found this site for Sumitomo p/n's, a lot of the sensor are of the HW sealed series p/n. (connector/pins/seals)

Still looking for the TPS/MAP sensor connectors

Gather these p/n's then find some cheap sources.

that what i meant, there is another iirc talking about connectors..

ago long time i took many hours finding info for milspec and oem connectors, when i have money and time i will try to make one for my SR20DE 

[jdmhatchracer94]

I wanna do this also but dont have patients to try and find all the part #'s and tools and pins etc FML gettin lazy

I'm getting the Sumitomo p/n's figured out, and I know Tyco is who goto for the ECU connectors and pins.

When I get it figured out I'll post the spreadsheet in this thread or in OG section. 

[PhilStubbs]

That would be awesome. I have always wished someone would. I want to build a harness mor my ef. It was a 91 std starting out. Now it is obd1, mpfi, pwm boost control, etc. it's pretty much impossible to make all those mods clean without just ripping the entire harness apart.

i will try to find all info i have in my old hd about this and post here..

Perfect, just what I was looking for. I need to build a harness for my brother volvo 2jz project using a aem honda box.

Lets start over.

I want to build an engine harness from ecu to my engine for both my Twincharge Civic and 3-stage vtec CRX.

I was looking at http://www.hondapartswholesaledirect.com/parts-catalog/honda/civic/1992/3dr-si/kl5mt/engine/engine-sub-cord-clamp

@ a cost of $371.36.

Then I was looking at Rywire
http://www.rywire.com/catalog/milspec-tucked-dseries-harness-p-49.html
But $599 starting is freaking nuts.

You don't need milspec.  Rywire non-milspec tuck harness retails at $399, I could maybe get one drop shipped to you for no shipping via xeno but IDK as their price break on those is minimal... in truth, Rywire's margins are really small, they are trying to make $ off of quantity.



Anyway, I've said it before, but J-series harnesses have most of the 90s engine plugs on the engine, and a BIG LONG stretch that goes across the firewall before going into the engine bay.  Scam one for cheap/free, cut apart and sleeve with DR-25 or braided loom, terminate in OBDx ECU plugs.

Russ, if you want somebody to throw some money in on a few 040 and 080 pins for the OBD1 plug end of things, I could cough up some money towards that.  You hold the money and do the transaction and ship parcels out when you get them.  Just make sure everyone understands a component order like that usually gets paid for first, produces 2.5 months later.

I'm really more interested in OBD2 Ford ECU pins, though.

[HiProfile]

I'm surprised you nogs even consider building a harness from scratch.

2 Used harnesses: $75 (one for your chassis, one from an unpopular chassis)
Solder, iron, heat shrink, heat gun, flux solvent: $75
Loom (either split or fancy fabricy shit that gets dirt into it): $25

I did the above when I made a DPFI harness into an obd0-obd1 EF harness, except the harnesses came with the car & swap. I just did it again for my Integra H/F-series harness. I got a D15 harness cheap ($110 for harness, p06, and p28) and an F23 harness on ebay for $10.99 shipped. I pulled the loom off, cut the short wires off the D15, cut longer pigtails off the F23 harness, then soldered them back together. I even got the wire that goes from the ecu to the shock tower from the F23 harness.

The process took maybe 8hrs, so say 16hrs MAX for someone w/o a clue. Even if you're a baller making $30+ per hour, that's cheaper than anything I've seen here. And you know it's done right.

Where do u get the dr25?

Curious, besides F23, and J-series harness what else could be used that is not super popular yet?

[HiProfile]

Aside from any obd2 4-cyl Honda, that's about it (for connectors). For wire, probably most german cars. But most people won't part out a car that nobody wants parts for anyways, or they crank up the price. I found 2 v6 Honda harnesses on ebay fairly easily for a decent price yesterday when I looked.

[walter]

havent much time really, i will check this week!!

[JHMED6]

I built my own harness re-using my factory harness. I was looking into buying new plugs and pins. I found most of the P/N for the male and female pins. It's annoying that the distributor pins are different than the sensor pins.

I used the nylon braid as my casing (similar to wireworx)

If I did it again, I'd make sure to use adhesive lined heatshrink on everything, and buy a heat shrink labeler.

Don't forget you'd need a crimper for all this, too. The pins are tiny. You might as well add a quick disconnect firewall plug, too. I wish I had done that... I want to make another harness...
