Quick Help! ECU Wiring and stuff! - Honda Prelude Forum

ludehawk · 05-23-2007, 02:27 PM

Hey, here are pics of what i'm dealing with...

If you're complaining about how big these are, you should get a better computer =p

Here's the mess:

Do I need these? aren't they for the tranny control thingy???

Do I need this? WTF is it???

What kind of ECU is this??? Is this good? lol

Lastly, on the VTEC solenoid wire, it was ran past the firewall and grounded at the ECU... can I ground it in the engine bay???

ALSO, what wires does it look like they tapped into, I don't see how these are pinned into the ecu???

THANKS!
I'm doing this now, so please help!

On a SEMI related topic. Is there ANYWAY to wire the clutch interlock so that the relay used isn't charged all of the time?
The clutch interlock must have a non-switched power source to charge the starter cut relay. BUT this causes the relay/switch to over heat.

The clutch interlock needs to remain functional, so how do i fix it so it doesn't burn out the switch and/or relay?

ludehawk · 05-23-2007, 09:17 PM

i dunno,

i just know i don't have a black box like that ontop of my ecu...

and when i wired vtec, i'm pretty sure we grounded to engine bay since it was right there

ludehawk · 05-23-2007, 09:22 PM

you're absolutely no help =p
i cleaned up the ecu wires. i'm thinking about using some of the pins out of the auto control box thing and using them on the ecu.
so that's a jdm p13?

ludehawk · 05-24-2007, 11:14 AM

the neutral switch question?

petern101 · 05-24-2007, 11:57 AM

ask billy because he did this (i'm pretty sure) with his car

the no start with depressing the clutch pedal mod to relieve pressure on something in your tranny...

and since you are fixing a car and asking PO, i expect my $75 and hour for diagnosing / replying with no useful information

bah, just help me wire the clutch interlock system without the clutch switch and/or the relay from overheating:

cripcrappled: yep, hot as hell, tape melted off
cripcrappled: because the switch is a neg trigger the pos is always charged
spin r g: whats the auto shifter
cripcrappled: it's tapped into the park/neutral trans control wire/same wire as manuals use for the neutral switch. but it's using a 5 pin relay, not a honda one
cripcrappled: and i can't tell if the honda one uses a diff power source
cripcrappled: i'm using a constant because when the car is starting, the acc and on are off.
