The last major part of the puzzle before getting the car tuned was installing the fuel system components. Smaller bits included wiring in the Hondata boost solenoid and 4-bar MAP sensor. In updating the fuel system, it involved some upgraded wiring too. I have done quite a bit of wiring now due to the air-to-water intercooler system and my work has gotten a bit cleaner.
Part of the upgraded fuel pump install was upgrading the wiring. The stock wire gauge for the stock low-power pump is tiny and it would have created too much resistance and voltage drop for the current draw of the new pump. For my modest crank 500hp target, I chose an AEM 340 pump. Science of Speed sells an upgraded fuel pump power wiring kit that utilizes the OEM Honda connectors that are well-suited for this size pump. If going to an even larger pump, I’d consider doing more direct wiring straight to the pump instead of trying to use the OEM connections. I ran the new power cable through this grommet hidden behind the (removed) battery. I poked a hole using a pick.
The wire came out here in the passenger footwell and I used the split wire loom provided in the Science of Speed kit to protect the wire on its path to the trunk.
I had this pry kit I bought from Modify way back in the day when I was doing car stereo upgrades. It came in handy for removing the various panels in order to route the pump power wire through the car.
With a few of the rear panels removed, this is where I routed the pump power wire. It sure was dusty back there behind the seat.
This is where the power wire ended up in the trunk. I haven’t had a spare tire in the car since I put on the Stop Tech brakes a dozen years ago.
