Can anyone pleae confirm that there are three relays secured to the wiring loom that is adjacent to the petrol injection management system within the passenger footwell
As standard there are TWO metal Bosch relays in the footwell loom. One switches power to the fuel pump and lambda sensor heaters, the other powers the fuel injector transistors and a permanent supply to the ECU piggy backs off the permanent 12v supply to this relay.mm33 said:

There are two, one each for fuel pump and injectors. On mine there is a also a third plus blade fuse. This was an afterthought by TVR as can be seen by the way it's spliced into the loom and fuse board. It controls one of the fans and for me it's activated by the original fan relay located on the main fuse board. This was an after sale mod done by TVR. The fans were drawing more current than TVR had allowed for with orginal single relay and fuse causing the fuse to blow intermittently. To fix the issue they later added a second relay and fuse. Maybe your third relay in the loom is this one too. It was done in 1994.Gassing Station | Chimaera | Top of Page | What's New | My Stuff
