J Posted May 15, 2006 Report Posted May 15, 2006 file not found so here they are The lumina pinouts are very different b/n the two clusters. I have no idea why, but I remember Whiskey River posted them a long time ago, and, IIRC there were like 5 wires that needed to be changed from base to upgraded cluster. For the Base Cluster C3 - Pink/Black - Ignition Power C4 - Yellow/Black - Low Coolant Light C5 - Tan/White - Brake Light (parking brake or low brake fluid) C6 - Brown -Charge Indicator C7 - Dark Green - Coolant Temp Indicator C9 - Black - Ground C10 - Brn/Wht - SES Light C11 - Tan/Blk - Shift Light C12 - Lt Grn/Blk - Antilock light (if so equipped) C13 - PPL - Fuel Level indicator C16 - Lt Blue - Left Turn signal D1 - tan - Oil Pressure Indicator D2 - Yellow - Fasten Seat Belts Indicator D8 - Gray - Dimmer switch D12 - Black - Ground D13 - Dk Grn - Speedometer D15 - Dk Blue - Right turn signal D16 - Lt Grn - High Beams Ok, here is the pinout for the gauges cluster. C2 - Black - Ground C3 - Gray - Dimmer C5 - PPL - Fuel Level C7 - Dk Grn - Coolant Temp C9 - Lt Blue - Left Turn Signal C11 - Yellow - Fasten Seat Belts Ind C13 - Tan - Oil Pressure Indicator C15 - Brn - Charge Indicator C16 - Yel/Blk - Low Coolant D1 - Dk Blue - RH Turn Signal D2 - Lt Grn - High Beams D3 - Tan/Blk - Shift Indicator D4 - Pnk/Blk - Ignition Power D5 - Dk Grn - Speedometer D6 - Black - Ground D9 - White - Tach Wire D11 - Pink/Blk - Ignition Power D13 - Tan/Wht - Brake indicator D15 - Lt Grn/Blk - Antilock indicator D16 - Brn/Wht - SES Light.

Crazy K Posted May 29, 2006 Report Posted May 29, 2006 I substituted 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 dismantled the voltmeter (no oil-gauge) cluster and input the info I discovered on it as well. The info here can help you to make any lumina cluster work. Disclaimer: I don't know if the all 90-94 base clusters are identical, please check this against your wiring, before you start. 1990, 1991, and some early 1992 Euro rally clusters have oil gauges. all other 1992, 1993, and 1994 have voltmeters replacing the oil gauge. Their are 14 seperate clusters used in Luminas that I am aware of: 1990 base cluster: thin lined monstrosity, with a light gray background 1991 - 1994: base cluster with a black ground 1990 gauge cluster: thin lined monstrosity with oil gauge and tach 3.1 redline 1991 - mid 1992 gauge cluster with oil gauge and 3.1 tach redline 1991 - mid 1992 gauge cluster with oil gauge and 3.4 tach redline mid 1992 - 1994 gauge cluster with oil indicator, charge gauge and 3.1 tach redline mid 1992 - 1994 gauge cluster with oil indicator, charge gauge and 3.4 tachredline and then each of those is available in english and metric specifications. GEEZ!!! the shift indicator, or filler plate, is interchangeable between all the clusters. I repinned my own connector. with practice and a good narrow jewelers screw driver it's quite easy. Just remember to tweek the lock tangs to ensure they lock when you reinsert. I would snatch an extra instrument cluster pigtail before starting and practice depinning and reinstalling. I emptied an extra connector and transferred the wires one by one to prevent confusion. Additionally, this swap requires a new temperature and oil pressure sender (if oil gauge cluster) in place of the original switch. The harness connectors are identical. Remember the length of the oil sender for the gauge is about twice as long as switch for the base cluster. 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 pin location. Then the wire color and description. The last number is where it has to be moved to in the euro cluster harness. 1990-1994 Lumina cluster base connector Pin# Wire color function bc-C1 --- not used bc-C2 --- not used bc-C3 PNK/BLK switched ignition feed, hot in run (+) D4/D11 bc-C4 YEL/BLK Low Coolant indicator C16 bc-C5 TAN/WHT "Brake" Warning indicator D13 bc-C6 BRN charge indicator C15 bc-C7 DK GRN Coolant Temp indicator C7 bc-C8 --- not used bc-C9 BLK Ground C2/D6 bc-C10 BRN/WHT "Service Engine Soon" indicator D16 bc-C11 --- (low fuel indicator if equipped) bc-C12 LT GRN/BLK "ABS" indicator D13 bc-C13 PPL Fuel Gauge input from sender C5 bc-C14 --- not used bc-C15 --- not used(low oil, if equipped) bc-C16 LT BLU Left Turn signal indicator C9 bc-D1 TAN Oil Pressure Indicator(grounds to light if no pressure) C13 bc-D2 YEL Fasten Seatbelt indicator(grounds to light) C11 bc-D3 --- not used bc-D4 --- not used bc-D5 --- not used bc-D6 --- not used bc-D7 --- not used bc-D8 GRY Illumination (adjustable backlighting) C3 bc-D9 --- not used bc-D10 --- not used bc-D11 --- not used bc-D12 BLK Ground C2/D6 bc-D13 DK GRN VSS speedometer input D5 bc-D14 --- not used bc-D15 DK BLU Right turn signal indicator D1 bc-D16 LT GRN High Beams indicator D2 Ok, here is the pinout for the Euro's fully instrumented cluster.

(ie shift if equipped) For (bc-C3 Pink/Black - Ignition Power ec-D4/ec-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. in a proper euro harness they link. For the tach, (ec-D9 White - Tach Wire, analog) 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(the C100 connector). 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 get damaged and shorted. Euro cluster ec-C13 and ec-D10 positions are two possible locations for the oil pressure wires. ec-C13 in for the guage, ec-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.
