Wiring Harness

Recommended Posts

Hi all.

Sorry to be annoying, I have done searches on loads of forums and the net trying to find a straight answer. But it keeps eluding me.

Im changing my stock headunit to a pioneer double din from my last car.

I have bought the JDM fascia kit.

What I can't wrap my head around is what wiring harness i need for it, that will retain use of the bose amp. I have seen different answers everywhere.


This harness says it retains factory amp use. I just dont know what all the different connections are for.

If someone could clear it up with me, would be much appreciated.

Yes, replace the factory amp.

I left my new JVC head unit (which has a 55w rms amp built-in) running the back/side 4 speakers, then ran rca's from the new head unit to my amp in the boot, then ran speaker wires for my new Soundstream/Tarantula front splits to run off off the new amp, with the 3rd/4th channels bridged to a 10" sub in the boot. You are welcome to come have a look anytime Sam - just don't pull me over for a look at it if you see me out and about - you will give me a heart attack! :):ninja:

Ahh awesome!

I think I'll just keep the rears as the subs. I don't want a sub anymore. Got 3 in my room in my house as it is!!

Can i just replace the amp? Means I'll just need to run rcas from head unit to amp?

    • Sounds like all you want is a button on your CAN dash pad that is for 2-step / anti lag launch.  Hold the button down, rev limit gets set to whatever you want, say 5000 rpm. Then mass timing is pulled and a heap of fuel is dumped in for fun times. Want more bangs and flames, pull more timing or add more fuel or both lol.  Obviously the more you use the fun button, the shorter the life of the entire hot side of your motor. So valves, turbo, cat, any sensors in the exhaust, etc etc. Well, if you are using it for its intended purpose it is very rewarding. If you are at the drags and want to launch on full boost, how else are you going to do that?
    • Engines are expensive. You already mentioned having thermal management issues with your car, anti-lag dramatically raises EGTs and can easily damage a cylinder head. If your goal is actually to improve transient response I recommend VCAM. DBW can also help here. Instead of a simple mapping of accelerator pedal position to throttle opening instead you interpret the accelerator pedal as a certain torque/power request and the throttle will open more or less to achieve that. So if your desired acceleration requires getting 0.5 bar of boost the throttle will silently go wide open to spool the turbos, then as it gets to that target intake manifold pressure it will adjust the throttle back to the steady state target. Another trick you can play is detecting when a shift is happening using a strain gauge and clutch switch for example and rather than snap the throttle shut when the accelerator pedal closes you cut fuel injection and hang the throttle open to keep the turbo from slowing down. This is a pretty complicated trick to play though as if it got stuck in that logic you would have engine runaway and you want to make sure the engine RPMs actually fall at a reasonable rate instead of rev hanging badly.
    • What sort of power difference do you think you'll see between the two engines? Is it just the extra RPM from the wide journal that you're chasing?
    • I did have a chat about boost when I was picking up the car, Mania recommended a little turbo over a supercharger for a 4 pot as the parasitic loss from spinning it up is substantial  Pricing was $13k drive in drive out for the 2.0 turbo package which can net around 180 killerwasps and alot more tourqes, or, add on top of that $13k, another $7k for a 2.5 swap with the turbo drive in drive out for a little more hsprs up top, but a big chunk more torque everywhere else  But no, I'm more than happy rolling around in the little 2.0 NA for a daily, all of the handling goodness, but none of the FI issues associated with putting FI on a stock NA engine and driveline If I wanted a "faster daily" I would have picked a different car The Bogan Cruise Ship is my car with boosted powers I feel I now have the best of both worlds, a fun and reliable little daily that I enjoy throwing/thrashing around town, and a big fat cruiser that has more power for the streets and Hwys than what I can actually use and still keep my licence Jackie has also decided that whilst she did enjoy driving the MX5, any shopping expeditions we do will be in her ASX, or the Commodore for long cruises or trips away, Jackie is much taller than me and isn't keen on folding herself into, or out of the MX5, she has hit her head on the top nearly every time she has got in it with the roof up, she calls it the stupid little matchbox car, LOL, perfect........
