Last night the dashboard instrument lights, parking lights and tail lights on my 72 240z shut down when i turned  the combo switch on. I noticed that the 15 amp fuse inside the fuse holder provided by Dave Irwin Parking light harness kit went south. Replaced it with  another 15 amp and even a 20 amp fuse dashboard lights, tail lights and parking lights came in for 2 seconds and the fuse went out again. I believe the problem resides in the harness upgrade. Last time this happened i removed it from the circuit and connected the stock female and male 6 wire connectors together and all the lights came back. Could there be an issue with the relays provided in the kit? Should i just check the parking light bulbs first and clean for any corrosión before removing the steering colummn cover and making the straight stock connection again?

Blowing fuses as you describe is a short circuit to ground, somewhere in that circuit.

Are you sure that you connected it properly?  Didn't nick any wires?

Don't put larger fuses in to fix a short circuit problem.  Find the short and fix it instead.

Find and fix the problem. I could be in the harness, relays. You just have to be systematic

I try my best to stay out of these but absolutely DO NOT GO TO A HIGHER FUSE.
