Ok I just got this rx7 vert to ls1 swap but I have a few.issues. The radio, room and top fuse keep blowing any clue as to why all three would guys

 

S4 or S5 and which top fuse are you talking about as there are two to choose from. Do these fuses blow w/just the key to on and all accesories off or what?

You're doomed. Clearly the rotary gods have put the dreaded oxymoron curse on the car.

 

You need to do some investigating.
Whoever did the swap had to interface with the stock harness, how that was done could be the problem.
At the bare minimum power had to be tapped but many more circuits may have been dinked with depending on the ambition of the installer.

You could have a combo problem- i.e., the vert top fuse blowing may be a completely Mazda issue, unrelated to any swap mods and the radio/room fuses could be a result of tinkering.

Do your gauges, the top, the radio actually work?
