Narrative:

First officer found #1 [main] wheel smoking with evidence of metal fragments during post flight walk around. This occurred on the ZZZ ramp due to a possible #1 wheel bearing failure. Mechanic X and I were dispatched to repair the dehavilland Q400. We removed and replaced both #1 and #2 main landing gear (medium large transport) tire and wheel assembly; both brake assemblies; both wheel speed transducers; and the left main axle.upon arriving at work; I learned the same aircraft was involved in a #2 tire blow out in ZZZ1 three days later due to an anti-skid issue. I looked in maintenance documents to read the defect report and learned the #1 and #2 speed transducers cannon plugs were swapped and installed incorrectly.I told my lead mechanic; supervisor; and station manager what happened and showed them in the aircraft maintenance manual (amm) task what we did and how the amm task is misleading. I told them the written steps were so easy and only dealing with two wires; mechanic X and I read the steps and performed the job without looking forward in the task [procedures] at the illustrations (figures).the amm tasks are very easy to accomplish; but they are also very easily deceiving by their lack of connection between the written steps and the illustrations. Removal task 32-11-04; step 4-A; note; says to tag the wires before unpinning them from the [cannon plug] connector. There is no reference to tag them specific to either #1 or #2 side [medium large transport inboard/outboard]. Figure 403; sheet-1 does show the wires to be specific in configuration. If the written step above said; 'reference figure 403 for correct wire configuration tagging;' we never would have made this mistake. The same language misconnection occurs for the installation task 32-11-04; step 4-A; note and figure 404; sheet-1.

Title: A Line Mechanic reported cross wiring the left main landing gear (MLG) anti-skid inboard and outboard wheel speed transducers during a field trip on a DeHavilland Q400. Approximately three days later; the #2 main tire blew on landing due to an anti-skid issue.
