Starter wiring

I just put in my powermaster mini starter with headers, my cable is stretched to its limit, need to fond one about 8 in longer
Yeah I ran into that too.
But I installed my battery into the trunk, and moved the starter relay to the passenger side, down on the frame next to the firewall and the headers. After that the oem wires were too long,lol. I routed them up over the bellhouse and down the other side.The battery tray is gone.
