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

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 :)

      Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS

      Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.

      Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.

      Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.

      R34 GT-T cycling ABS pump

      There is an ABS pump and a few solenoids. You could trigger the front/rear solenoids with a pressure bleeder attached with a Consult 2.
