Hey all. I took my rear seats out on weekend so i can take the rear shelf off to fit speakers and found under the shelf a connection to a box that the wiring wasnt attached to. It was mounted in the bracket on the drivers side in the cavity beside the speakers. On the other side there was another bracket but nothing in there. Any one have any idea what that is and what would happen if i connect the plug back in.

Sorry for the vague description. I was meant to take a photo but forgot.

Thanx in advance

HICAS Computer

No i dont think so. This box is IN the cabin. not in the boot and it is unplugged. my hicas light isnt on and i know it is working.

If i am wrong and it is the HICAS computer i will feel very foolish :/

Hmm, a photo would really help right now. Does the box have any markings on it at all ? My HICAS Computer was mounted under the rear parcel shelf, on it's own bracket. Did you check that a HICAS Lockbar hasn't been installed ?

Lock bar isnt installed. I will take a photo soon to try and show you. It has no markings on it at all. My HICAS is mounted in same spot but this isnt near there. I was wondering if i shouldjust connect the plug but worried bout what it might do

Obviously the car works fine without it, so I'd leave it disconnected until you figure out what it is. I'm intrigued now :laugh:

The factory amp was designed to be used with the factory tapedeck, Nissan's "active speaker" system. Most likely been bypassed if you have an aftermarket headunit in that already has MOSFET builtin or an external amp.

The R32 one irc is marked Clarion, no idea what the R33 might be marked as.

That could be it but it isnt circular. it is a rectangle shaped box. When i get a chance i will take a photo of it.

Thanks for your suggestions guys.

well on my 33, there is a box exactly as you are describing on the left hand side (drivers side), and there is the same bracket on the right but no box. this is the HICAS ecu. it may be possible that the last owner disconnected it and removed the globe from the dash (i know people do this) so they can pass the WOF.

but if my HICAS light still comes on upon start up then that couldnt be it. but what you have said is exactly how it looks with the seats out. I am still confused lol. Maybe ill plug it back in and see

Mine has the same, and to the people that are confising it with the HICAS computer, its not. It cant be accessed with the rear seats in. Its mounted just above the shock tower.

I only found it in mine when i changed springs. Scratched my head a bit, and forgot about it :)

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
