s14 battery relocation/wiper problem

[the a3k]

ok i recently finished relocating my battery to the trunk. Everything went smooth i guess but apparently now my wipers aren't working... WTF. I checked all the fuses and they're fine. The only other thing i did was install a new headunit but that shouldn't matter. Anyone have an idea what could be wrong?

Here's my setup. I used a distribution block in the engine bay to connect all the wires instead of using electrical tape. I ran the positive cable through the rubber grommet that the ecu wires run through the firewall. In the trunk have a inline fuse on the positive cable just so my car doesn't burn down. The ground wire is temporarily screwed in where the spare tire sits. For my battery I used a moroso battery box.

Either jus tby chance your motor is fried or you need a better ground. First I suggest is to unhook the plug and test for voltage when you have the wipers active. See if power is getting there.. Regardless you need a better ground which may solve it
