I have a few question so please hang in there. I am an avid forum researcher and from my lack of knowledge or understanding....., I am left with a bunch of unknowns.
Stock Info: 92 Chevy S10 Reg cab 2.5L engine with 700r4
Current state: Pulled out motor and trans, will be installing a 383 carbed (no choke) paired with a TH400 3000 stall NO lockup tranny.
Removed ECM and ECM wiring (Passenger side wiring), Will be a track truck primarily, A/C components removed, will run heat only.
I want to run everything from the wiring coming from the gauge cluster.
Gauges and accessories I am looking to run.
-Speedometer, Tach, fuel, volts, water temp, and oil pressure gauges
-Flexalite 480 fan and aeromotive A100 fuel pump.
Here is my wiring diagram.
.
I am a little confused on how to hook up my gauges. I have built a gauge cluster to house my (5) gauges, turn signal lights, and hi beam indicator. My quest is to wire all this without a hitch. :sweat: The numbers below correspond with the wiring diagram in the instrument cluster.
1. Gray - Instrument lamp fuse - There are 3-4 of these, one is in the oil pressure sending unit wires, another in a relay and the other two went into the ECM but are not connect now. All these wires are spliced together with the main one coming out of the ignition harness. I just want to know what it is or does and if I need it? My guess is its for dummy light activation if so then why are they all spliced together from one, how would the gauge cluster know which light to activate?
2.Pink/Blk - 12V ignition - I believe this will be connected to all 5 of my gauges (+) post? Also needs to go to alternator (3 wire).
3.Brown - Alternator - Volts gauge send wire
4.Tan/Blk - ECM Pin A2/Up shift light? Not sure if I need it or what its good for in my application?
5.Tan/Wht - Rear wheel anti lock (RWAL) & Ign Sw Pin G2? I removed the RWAL stuff but not sure if I need this wire or what it was for?
6.Dk Green - Water Temp sending unit, will go to gauge sender post
7.Dk Blue x2 - Dir/Haz lights, right turn signal - Right Turn signal light in dash
8.Pink - Fuel tank unit - Im guessing this powers the fuel pump
9.Tan-Oil pressure switch/sending unit - goes to oil pressure gauge post but also wondering why this wire has a orange and gray wire with it?
10. None
11.Brown/Wht - ECM Pin A5 (SES indicator) No idea what this is for or is?
12.Pink/Black - Same as #2, 12V ignition - Can I use this for my electric fan for power?
13.None
14.Lt. Blue/Blk -Speedometer/ Speed signal output - Dont think this will work since I removed ECM? Can it be used for anything else?
15.Yellow - Audio Alarm module - For fasten seatbelt light- wont be using this in new gauge panel setup
16. Lt. Green - Hi beam indicator light - Will go to blue light in my gauge panel
17. Black - Ground - Will be used to ground all my gauges
18. Lt. Blue x2 - Left turn signal and dir/haz light - will go to left turn signal light
If any of these are incorrect or you know the answer to my unknown please help a brother out. First time doing wiring and I dont have family who are into this kind of stuff to help out.
Lastly, I know tach I will run a wire from Coil to tach to get signal.
Speedometer I havent figured out but will wait on that till the end.
Other wires I have in my bay are this:
Orange (4-5) - 12V Constant
Red - Goes to Alternator
Purple - Starter
Thick Pink - Coil
Gray - Not sure what its for, same wire that is going into this relay below and spliced into the main gray wire coming from the instrument cluster I mentioned above. Believe it is a fuel pump relay? But why is oil pressure lines going into it also?
What I'm working with.... Please help!!!
Any questions please ask.
