Not entirely sure if this forum is still active, but I recently picked up an '88 wiring harness to toss into my '87 and I got it and am entirely too confused on where to start. Electrical stuff doesn't really click for me, but I'm trying to figure out what connector goes to what and where to start. I can't find any diagrams labelling it so this might be a shot in the dark, but any help is greatly appreciated.

I was following a guide to reset my tps/isc because my '88 is idling around 1300. Got to step 4 and didn't notice any "zip" and the multimeter showed a constant 4.6 volts the few times I retried instead of the .9 volts it is supposed to show. Is there anything I can do besides go through looking for exposed wires that may be interfering?

What does this black bare wire go to? Can you tell me where to attach it?

I need the fusible links under the hood, 2 red 1 brown and 1 green. Anyone have any good ones??? or make them?? also maybe a fuselink b box?? thanks, i am in kissimmee florida 34743 thanks

So here is my list of all my upgrades, yet I still can't get a constant 14.4 nor even a constant 12 volts. Even if I turn off everything at times the car takes forever to charge up, or if the headlights are on it will only show 10 volts. Maybe you guys can help me decide what to do next.. Charging: 4ga ground from alternator to engine block 6ga piggyback wire from alternator to battery for increased charging capacity (with fusible link) dual factory sized fusible links on charging harness from alternator to battery (going to a single 12ga fusible link with the single 6ga charge wire next) Note: When car first starts power shoots to 14 volts. if I turn on lights, heater, radio and everything it comes down to 12. If I sit at a light with brakes lights on it may drop, it may not, if I sit at a stop with a turn signal it will start to decrease, but nowhere near what it used to, the surge of the blinker is almost unnoticeable now. Note: driving with radio and all accessories off did notice the voltage fluctuate when I hit a bump..? this is random and it's not by much Note: driving at night with lights on will cause voltage to drop, driving at 2k rpms will sometimes recharge the voltage, sometimes faster then others, sometimes it hangs at 10v for a mile or two Stereo: 4ga wire from battery to-- 100 amp inline fuse after battery to-- 4ga wire to 1.25 farad capacitor to amp-- 4ga wire from cap to inline 100 amp fuse-- 8 ga wire from 100 amp inline fuse to amp amp is grounded with 8ga--cap is grounded with 4ga to the bolts that hold the electrical device in front of the spare tire.. Note: Sound system seems to be in perfect order with almost no/if any power surges under bass. Ignition: cleaned up ignition switch-- replaced hot wire from connector to switch with 8ga wire soldered in on original terminals(yes it fit) Note: this made my lights brighter, my wipers work faster, the turn signal surge almost disappear, blinkers blink faster, heater blows harder.. Added: 35w 6000k VVME HID kit, I am now HID spoiled Removed: AC condenser pusher fan (it was burned out and suspected amperage draw) Coming soon: Blower Fan replace (Heater seems to draws a lot of power, normal maybe?) Rad fan replace (old motors can draw high amps if they are worn and on their way out) thinking about: CS130, maybe even CS144 mod Secondary battery in trunk (Maybe just replace front with bigger in the back in Battery box) Overall my charging and electrical is working top notch, when it works correctly. With stereo turned on full blast it will hold 12v for a good while. I have gone through every ground on the car IAW with PQ's write up. I'm thinking my alternator is questionable but hate to replace it with another OEM and get another headache in a few months, opinions on this? since I can't get a bracket for a cs130 I'm working on manufacturing my own next week, but I can't take the car down except on sundays and it has to be back together come monday morning. I am also thinking of going to a big blu marine Optima in the trunk either as my primary or secondary battery any opinions on this? I'm thinking of going to a CS144, same size as a CS130 but I can get it in 140amp size with the iceberg case cheaper than a OEM alternator so I may do that, the camaro is currently apart for preps for the season so I will be using the CS130 out of it for building the bracket. I guess if anyone can think of a wire I missed or a terminal I should clean let me know so I can work these gremlins out. Thanks in advance.
