Resistor Box Questions for Civic DX, Precision 780's, Neptune
« on: November 11, 2011, 03:07:28 AM »
Before I go frying something out following a random writeup, I figure I should ask. How can I wire up this resistor box with these mods in mind? Thanks!

99 Civic DX
Conversion Harness (and I dont remember if it was obdII to obdIIa or vice versa, etc)
Neptune Ecu p28 converted
Precision 780cc Injectors
Resistor Box

Power on the red wire, run the black wires to individual injectors.

I just did this to a friends 96 obd2a so I don't know if it is the same as yours being a 99.

Under the intake manifold there is a 'dead man's plug' that supplies 12V+ to all of your injectors, as well as some other components.
Remove the blank plastic plug and find a junkyard replacement with a short length of wire.
Unpin your resistor box.
With a volt meter find out which 4 pins go to your injectors and unpin them from your new junkyard plug, repin them with your 4 black resistor box wires.
twist and solder the remaining JY wire leads to the red wire from your resistor box.
plug your new plug with resistor box in place of the 'dead man's plug'

Sorry its hard to describe in text for me.
I'll see if I can get some pics or at least an ms paint to make it more clear, but it will be plug and play with no stock harness damage.  You can go back to stock, or swap high imp. injectors in without needing to cut or solder.

You could do it a better way.

Buy some bosch or denso's that are high-z and not fuck with the box. Precision injectors are delphi, which is old tech atm. Even gen1 deka's are better.

Yes, the easy way. So literally connect the black wires to the ground of the injectors? I have done the inline resistors on 450s but since people tie this into the harness its confusing me probably more than it has to.

Moar info on this sir

Think of this as resistors with pigtails, where the "dead end" possitive side are already twisted together. There has to be a million writeups on it on the net.

I'm starting to understand why the website keeps shitting a brick. :P




Here's one that shows the wires. It's the four yellow wires on the plug near your clutch reservoir.

3rd post on that link shows it perfectly.
A dizzy plug off an 90-00 accord works nicely...

Thanks everyone for the input. Its been a few years since I have done any modifications on cars besides general maintenence so I am beyond rusty. Its coming back to me though slowly though.

Will have pics up in about a hour when I am done to see if I wired it right. Thanks again

I think all cop cars need to have turbo. nbspnbsp Then they would understand the necessity of putting your foot down and how uncontrollable the urge is to fucking rail on that shit.
