My Allis 175 tractor came to me with most of the electrical wiring under the dashboard disconnected or miss-connected. With the help of the operator manual and parts manual I've been able to figure out how to correctly connect the lights, gauges and starting circuit. However, I haw two wires left with factory ends on them that I need help on determining what they do and how to connect them. One is a blue wire with a white stripe with a pigtail on it (see picture) the other is cream colored like that of the flasher circuit. Any ideas? Thanks.

If I recall, the operator's manual describes the wire color. You can also trace the wire to see where the other end goes. The operator's manual was super helpful when I put a new wiring harness on mine. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

just a guess.... but the 170 diagram shows a BLUE wire going to the rear work lite and the TWO wires on the flasher are both an off white color...... 4 and 5 to the SAFETY start switch are also a white color.. ------------- Like them all, but love the "B"s. |

| Thanks for the reply. Steve, lines 5 and 6 are washed out in the photo. What wires do lines 5 and 6 describe? Thanks again |

| Thank you. This helps a lot!. My recently purchased manual has the wiring diagram with just numbers on each wire but is missing the pages you photographed. Hopefully the 170 and 175 are wired the same. From the wire tracing I'd did on my 175 they appeare identical. Thanks again. |
