car is throwing two codes, PO135- 02 heater (h+r - 11) CKT (b1, s1) and PO155 (h+r - 21) CKT (b2, s1)
the codes are for the front 02's, its both of them so i doubt theres actually something wrong,
does anyone know what fuse the front 02s run with? or anything else that could cause this?

Here's what the shop manual says about those codes...
All four O2 sensor heaters are powered from the same source, fuse #8 in the central junction box (under the dash).

It is a power/wiring issue with the heaters for the front sensors, recheck the connectors...
Here's the wiring harness diagrams for the driver's side front (HEGO #21), and the two rear sensors; and the passenger side front (HEGO #11).
