VTEC_4_LIFE · 07-26-2008, 09:25 AM

im gonna be getting an Apex-i RSM soon, and im gonna need to wire it into the ECU. . . just need to know where it is, and if anybody has a color coded pin-out guide that would be wonderful as well

civic_coupe · 07-26-2008, 10:06 AM

isnt it under the hood? above the battery...?

VTEC_4_LIFE · 07-26-2008, 10:42 AM

ill check when I get back home from work. . . but if thats the case I think I might try wiring it to the instrument cluster leads

civic_coupe · 07-26-2008, 11:00 PM

VTEC_4_LIFE · 07-27-2008, 01:22 AM

I'm pretty sure the ECM i inside that black box there.

Didn't I see someone state that the Civic ECU is the box under the driver's seat?

VTEC_4_LIFE · 07-28-2008, 10:19 AM

well either place is believable, if it was under the seat that would make my install LOADS easier, thats for sure. . . ill check both, I just gotta figure out how to pop off that black cover on the under-hood location

All you have to do to pop that black top off is to just pull it towards you. It should just come out easily.

VTEC_4_LIFE · 07-28-2008, 10:58 AM

yeah ill try that when I get home

GlassDoctor · 07-28-2008, 11:07 AM

the black thing you circled is just a cover that slides right off. I wouldnt mess with that thing myself. I hope it is actualy under the seat.
