I want to convert my crx OBD0 to OBD-1. I heard that you shouldn't cut and solder the new dizzy plugs on the original harness since it messes with the polarity or some crap. I don't want to buy an adapter harness sine it is pretty much doing the same thing with the connectors. what does everyone recommend?

since this is rhmt i'm pretty sure we all solder our crap right?

uhhhh yea

[ApexSilver06MR]

everything is color coded and soldering the connectors are fine...

[chris]

Whoever told you that stop hanging out with them. Who are these people

[Jorsher]

lemme guess, joker4096 on crxcommunity

Solder won't fuck with polarity...lol.  People suggest it since you get a better connection than just twisting wires together, but I'm lazy and haven't had a problem with it.

[chris]

So you cant solder wiring anymore, damn.

[snm95ls]

Heh.  I guess the OBD0 plugs that I soldered onto the OBD1 distributor in my blue hatch should keep it from running properly...


As Chris said, stop hanging around or listening to whoever told you this.

No it certainly does flip the polarity.  Basically you can't just solder some but not the others.  If you solder them all the polarity is flipped on each one and they cancel out.

Unless I have completely missed the boat on electrical theory, how in the fuck do you figure?

[ctr99ek]

i guess i meant voltage, not polarity, wtf was i thinking hahaha

I think you missed his sarcasm, sir.

its going to flip the voltage now? 

positives become grounds.  yes, that happens, when a retard starts connecting the wrong wires.

Even if soldering the dizzy wires was an issue, have you not heard of solderless connections?

[snm95ls]

Soldering the wires doesn't cause any adverse effects.  I soldered OBD0 connectors onto my OBD1 distributor.

Somebody is full of shit.

I'm well aware of that.  I'm saying, even if somehow, magically, you couldn't solder the wires, you could buy some solderless connectors and that would work perfectly.  The OP clearly is just flat out retarded.  He deserves to hang out with his retarded friends.  They compliment each other nicely.

Fuck all this talk soldering guns cost to much. use garbage bag twists to hold you connections together.

I just hire Buk to do all my electrical work.  He is an expert!

The only real problem is that the crank angle sensor wires are shielded and VERY picky. First I did a clean install with a fully wrapped obd0-1 dpfi-mpfi harness, which failed after a week. Can't rev over 3k. Then I did a dirty direct wire with speaker wire. Worked sometimes, others same bullshit.

Then I got some shielded 22ga wire intended for phones. It worked flawlessly afterward, and I don't think I even had to ground the wires. FYI I can't recall the exact sensor name, but it's whatever you ADD to an obd0/dpfi setup to make it obd1/mpfi.

see there was something to worry about.  geez you guys can go suck one, the negative contributors

Because using shielded wire on a VRS signal is rocket science.

Totally the same as soldering the wires and reversing the polarity.

get bent.

[bouncinofftherevlimiter]

on my brother in laws (ex B-I-N now??) ricetastc CRX, we just popped the pins out of the connector for the obd1 dizzy and put the obd0 connector on it, there was no soldering and it looks original...

is that maybe and option for you to look into??

[ratcityrex]

I just repinned my stock obd-0 wires, to a obd-1 plug. And the one pug that had 2 wires I just cut and solder with the obd-1 plug. Its Eazy, just goolge it.

[rsmith2786]

Just fucking solder them.  It's fine.  It's not like every wire has a flawless path from the engine to the ecu.  There are connectors, interference, and on top of it all Honda uses the thinnest possible wire to save every penny then can.  What do you think happens to that wire when it enters the ecu?  It's immediately faced with a soldered connector from the header and every other connection on that board is soldered.

[jagojon3]

DANGER TO POLARITY

Solder is the devil

Use zip ties and lots of loops in the wire to save polarity

[michigan_soler]

Come on now. Just cut each wire twice and hage two solder stops on each wire... it fixes everything....

Fuck it. Just run solder in place of the wires.

TIG weld. only way to get a solid connection.

God damn it. I have no spark. I made a jumper harness at one point to convert my DOHC ZC from OBD0 to OBD1 (harness side, not the dizzy side). Then i cut that off, and converted to OBD1 plugs (engine harness, not dizzy). Now as Im going through wiring diagrams to find why I have no spark, Im reading that some of the distributor wires are "shielded". WTF does that mean? Any chance that would keep me from getting any voltage to the coil (black/yellow wire)?

It ran fine all last year. Went to fire it up this year after doing a bunch of other shit, and it wont run. I didnt touch that part of the harness though.
