ELECTRICAL PROBLEM?

[180sx]

So i know this may not be the place to ask but its somewhat ka-t related or some of you may have delt with this issue before/since i went ka-t i have been having few problems here and there

VEHICLE 1989 240sx hatch

1 my dash lights were blinking one day going on /off and than just went off !same with my rear light s they won't light up when i turn them on !brake lights work! speedo works turning /side markers etc. now in tech forum i was told that its my fuse under the hood , checked :they all fine same with kicker pannel fuses . so than someone sad bad ground , took my dash apart founf 1 lose purple wire not sure where that goes ? anyone

2 Seems may be related to #1 / since ka-t i use those blue ngk wires , so the other night i hear valve ticking so i am like wtf the engine was just rebuild with oem parts less than 100kms ago / so i open my hood and its defenatley not valve tick its a Spark jumping from my spark plug wires # 1 and 2 to the head where they plug into the spark plugs why would that happen brand new wires

3 again may be related to the first 2 / here and there my car stumbles in 2nd around 3500rpm like it revs up and stops around 3500 like its unpluged maf but than i let gas pedal off, and hit it again boom goes all the way to redline like no problem .

the car isn't my daily driver so since rebuild and ka-t i haven't driven it much to see what else / meanwhile i am going to do more "search " if someone can help me meanwhile with some replies that be greatly apriciated

If you have a bare wire from chaffing then you'll get that spark problem.

What are you running for engine managment?

bare wire from chaffing ?...... where is that? no engine managment just ka ecu, all factory fuel delivery.

well i figured out the bogging part yesterday ...of course the boost leaklights update ... no lights stil haha so only lights i have is interior cd deck and headlights and turning signalno dash no corners no back lights.
