low voltage to twist grip sensors 1 & 2

[kiwisteve]

H yesterday I put tune eco map in, huge , difference however in an attempt to disconnect headlight I pulled the large grey plug behind panel above headlights. That cut all power so after plugging it back in it came up traction control disabled and grip sensor faults, also now only the right front indicator works
I erased the fault codes, prob not smart as now I don't know the numbers but traction control seems ok but my 3 indicates still don't work yet it still flashes like normal on dash
does anyone know where I should be looking to get my indicators up and running
any help greatly appreciated
