The local junk yard has a 1990 RRC that I want to remove the speedo and see if it will fix my 87 inop speedo but is it compatible?   Land Rover Certified Used A**hole (Jason) Senior Member Username: Jason Post Number: 472 Registered: 04-2002 Posted on Wednesday, April 23, 2003 - 10:15 am:    Both the '87 and '90 have a cable running from the VSS mounted on the chassis to the transfer case. The '87 has a second cable running from the VSS to the speedometer. The '90 does not have this cable; it uses the electric signal produced by the VSS to calculate the vehicle speed. The VSS' on the '87 and '90 are the same part number, IIRC. You will need to figure out some way to jumper the output of the VSS and route it to the speedometer. I'd venture to say you may be better off pulling the entire instrument cluster from the '90, but you'll have a new boat of problems if the wire-harness doesn't jive between the '87 and '90. Can you do it? Sure. You'll need a wire-diagram and a lot of patience to pull it off...   John Cinquegrana (Johnc) Senior Member Username: Johnc Post Number: 430 Registered: 07-2002 Posted on Wednesday, April 23, 2003 - 11:23 am:    I have the re-wiring diagram (got it from someone on this board). I will look for the files and post them this afternoon.   Rob Davison (Nosivad_bor) Senior Member Username: Nosivad_bor Post Number: 250 Registered: 02-2003 Posted on Wednesday, April 23, 2003 - 12:02 pm:    john, i have a spare 88 RR with speedo. maybe you can buy mine ands save yourself some trouble? let me know rob   John Cinquegrana (Johnc) Senior Member Username: Johnc Post Number: 432 Registered: 07-2002 Posted on Wednesday, April 23, 2003 - 12:44 pm:    http://images.andale.com/f2/115/106/3653414/1051113739921_rangerover1.jpg http://images.andale.com/f2/115/106/3653414/1051113733767_rangerover2.jpg http://images.andale.com/f2/115/106/3653414/1051113719221_rangerover3.jpg http://images.andale.com/f2/115/106/3653414/1051113713124_rangerover4.jpg http://images.andale.com/f2/115/106/3653414/1051113710789_87RRINSTRCIR.JPG http://images.andale.com/f2/115/106/3653414/1051113709296_87RRINSTRREAR.JPG http://images.andale.com/f2/115/106/3653414/1051113707396_90rril.jpg   Thomas Dahbura (U352) Member Username: U352 Post Number: 109 Registered: 10-2002 Posted on Wednesday, April 23, 2003 - 01:13 pm:    Buy the speedo or the Rangie?   Rob Davison (Nosivad_bor) Senior Member Username: Nosivad_bor Post Number: 254 Registered: 02-2003 Posted on Wednesday, April 23, 2003 - 01:42 pm:    THE SPEEDO.. or the whole thing, it's a parts car.
