F355 UK imobilizer removal help
Discussion
Well it has lasted 30 years, 22 years with me and it finally let me down by cutting the power of to the fuel pump and not letting the car start. So it's time to get it out.
This post is the beginning of my quest to find any information on how to remove it. I need to know what wire does what and how to wire back up the standard factory wiring.
I believe the system was retro fitted to UK 90s ferraris and porsches, and was made by Hamilton & Palmer. This unit has the little spade that has to inserted into the slot. I know were the control box is, I just need to know about the wiring.
There must be 355 owners that have removed this system and know details.
Thanks for any help to any one who might respond.

If this isn't detailed enough, Fchat may be a good source of advice. Note: I don't own a F355 and have no knowledge of these cars.

Hi Fez
I've had a quick look through various forums (bored!), and there was a guy on 911uk who had his PA1000 removed (in 2019) by Dragon Alarms in the Portsmouth area. I don't know where you are but maybe you could call them for a bit of info? He dealt with Inti Patel, who I think runs it, if that helps.
I've even googled the phone number.. 01329 446322 (I hope it's correct!)
Let us know how you get on.

No worries.
I'm no expert on this but I do have a 355 and a 964. The 964 has a PA1000 that I'm now thinking I should remove!
From the little I've read, I understand that Hamilton and Palmer have moved on to different things and no longer support this alarm.
The chap who was a fountain of knowledge apparently retired a fair while ago.
I may be incorrect, but as I understand it, the wires from the alarm are all black(?) so you won't know which is which. I think it's a case of tracing each of them back to the loom, disconnecting them and repairing where they were spliced in.
Go for it! What could go wrong? - I'm sure it's as easy as it sounds!!
ETA: I'm guessing that more of these were fitted to Porsches back then than were to Ferraris. My Ferrari doesn't have one and I've never seen one on a 355 that I can think of.
Good luck getting it sorted.

I don't think this is an original fit is it? Both my 355's had the black fobs (and car came with a red one for reprogramming) I had one the same as yours in my Porsche 968 Club Sport and as somebody has said all the wires from the unit are black, I guess most of them are going to the panels behind the seats, fro memory the original immobiliser was on the passenger side and ECU on the Drivers, I'll have a dig as at one point i had a printed 355 Manual with wiring diagramsThis post is the beginning of my quest to find any information on how to remove it.

Hi, yes I bought spare Insert key from ferrari in Birmingham about 15 years ago. I gave them the reg of the car and they got a brand new one in the next week.They was fitted to what seems like some 355s as well as porsche 993s.
Mine is the 2.7 so the ecu is not behind the seats. But one at each side of the rear of the engine bay.
But any advice is welcome, thank you.

This was the spare insert key that was bought from stradstone ferrari in Birmingham about 15 years ago, complete with the cavalino on it, as well as ferrari UK. The parts guy called shadow sorted it for me a well as a a spare new ignition key . So I believe this was a known retro fit to some ferrari's during the 90s that ferrari clearly knew about. They sorted me a spare key out just from my reg number.
I have seen a few UK cars with this system.

Yes dead easy. I used to fit all that kind of stuff back in the day.
Follow the wires from the key socket to the box.
Three circuits, two earths, one power and a +15.
All wires are black so you’ll have to trace to where the installer made the cuts. They were supposed to cut 300mm of wire out between cuts, as per VSIB regs at the time but not many installers bothered so it’ll probably be really obvious and you can just re join the cuts and you’re good to go.
Most likely fuel pump, starter and a coil feed.

That fob is identical to 928 fobs - just a different sticker I have seen a few UK cars with this system.

Porsche GB had Hamilton & Palmer install these to the 928.
Maybe worth some cross referencing ? DV has an ECU available

Well the update is that it's now been removed and put back to original without the bloody imobilizer.
Dam, behind the passenger foot well fuse board, the factory wiring was un organised. I can see why early ferrari's had a reputation for bad electrics lol
Thanks for the replys.
