Crazy K Posted December 17, 2005 Report Share Posted December 17, 2005 This should be put in FAQ This is to substitute a 1991 euro cluster with oil pressure gauge in place of a regular cluster. The project vehicle is a 1992 lumina sedan. However, I have also dismanlted the oil-gauge less cluster and input the info I discovered on it as well. The info here can help you to make any lumina cluster work. Info: I don’t know if the 90-94 base clusters are identical, please check this against your wiring, before you start. 90 and 91 Euro clusters have oil gauges, 92-94 have voltmeters. This may be an exception for Z-34, I believe they may keep the oil gauge for all years. I repinned my own connector. with practice and a good narrow jewelers screw driver it's quite easy. Just remeber to tweek the lock tangs to ensure they lock when you reinsert. I would snatch an extra instrument cluster adapter before starting and prcitce depinning and reinstalling. I emptied a connector and transfered the wires one by one, so I wouldn't get confused. Additionally, this swap requires a new temp and oil pressure sender (if oil gauge cluster) in place of the original switch. The sensor harness connectors are identical. Remember that you have to order one from a 90 or 91 since 92 up 3.1 luminas don't use a sender. Remeber the sender is about twices as long as the switch. The top row is C, bottom row is D and they go 1-16, left to right. For the Base Cluster First number is the base cluster location. Then the wire color and description. The last number is where it has to be moved to in the euro cluster harness.

First number is the base cluster location. Then the wire color and description. C1 NC (Tan/Blk? ie shift indicator if equipped?) C2 Black - Ground C3 Gray – backlighting C4 NC C5 Purple - Fuel Level C6 NC C7 Dark Green - Coolant Temp C8 NC C9 Light Blue - Left Turn Signal C10 NC C11 Yellow - Seat Belts C12 NC C13 Tan - Oil Pressure Indicator(NC if no guage on 92+) C14 NC C15 Brown - Charge Indicator C16 Yel/Blk - Low Coolant D1 Dk Blue - Right Turn Signal D2 Light Grn - High Beams D3 NC (Tan/Blk? - Shift Indicator if equipped?) D4 Pink/Blk - Ignition Power D5 Dark Green - Speedometer D6 Black – Ground D7 NC D8 NC D9 White - Tach Wire D10 NC (this is the oil light position if no guage on 92+) D11 Pink/Blk - Ignition Power D12 NC D13 Tan/Wht - Brake indicator D14 NC D15 Lt Grn/Blk – Antilock D16 Brn/Wht - Engine Light KEY: NC= no connection, no wire was present, if there is an optional light I listed it. (ie shift if equipped) For (C3 Pink/Black - Ignition Power D4/D11) this power wire must be spit to have a second wire , as the base cluster has one socket and the full guage cluster has two. For the tach, (D9 White - Tach Wire) this wire is absent from within the car. I discovered that the tack wire is a small gauge white wire in the harness that meets the firewall behind the alternator. It does not continue past there into the body. Open up this wire loom and you’ll discover bunch of wires. Only about 5 are small gauge, and the white wire will be obvious. Link it from there and run it inside the car to the cluster. Be sure not to have it run where it will not get damaged and shorted. Euro cluster C13 and D10 positions are two possible locations for the oil pressure wires. C13 in for the guage, D10 for the idiot light. This is the only know difference I have found between the two types of clusters. This is a possible difference, I didn't track this info very well, but Euro cluster D1 and C3 (ie Tan/Blk? ie shift indicator if equipped?) either appear to be possible locations where a manual trans car would have up-shift, or down-shift indicators. I didn't have a year break down for these, sorry. One last issue, some pins actually are identical to other pins, so a wire could be in a slightly different position (ie C7 instead of D7, fake example) this issue is usually the same number pin but different letter (ie C7=D7, or D13=C14, fake examples) This is visible on the back of the circuit board as the circuit line will run through both pins. -Ken I've done some editing to clarify and correct the info contained.
