Excerpt from MIL-DTL-26482H
3.7.4 JAN and J marking. The United States Government has adopted and is exercising legitimate control over the certification marks “JAN” and “J”, respectively, to indicate that items so marked or identified are manufactured to, and meet all the requirements of specifications. Accordingly, items acquired to, and meeting all of the criteria specified herein and in applicable specifications shall bear the certification mark “JAN” except that items too small to bear the certification mark “JAN” shall bear the letter “J”. The “JAN” or “J” shall be placed immediately before the PIN except that if such location would place a hardship on the manufacturer in connection with such marking, the “JAN” or “J” may be located on the first line above or below the PIN. Items furnished under contracts or orders which either permit or require deviation from the conditions or requirements specified herein or in applicable specifications shall not bear “JAN” or “J”. In the event an item fails to meet the requirements of this specification and the applicable specification sheets, the manufacturer shall remove completely the military PIN and the “JAN” or the “J” from the sample tested and also from all the items represented by the sample. The “JAN” or “J” certification mark shall not be used on products acquired to contractor drawings or specification. The United States Government has obtained Certificate of Registration Number 504,860 for the certification mark “JAN” and Registration Number 1,586,261 for the certification mark “J”.

WIRE-STRIPPING AND CONTACT-CRIMPINGAMPHENOL MB SERIES WIRE-STRIPPING AND CONTACT-CRIMPING
STEP 1: Strip wires. (See above for correct strip length by contact.) Insert wire into rear of contact. Wire insulation must push against rear of contact. Wire must be visible through inspection hole. STEP 2: Use M22520/1-01 crimp tool with proper crimp locator M22520/1-02. Click here for additional tooling. Contact Size Color 20 Red 16 Blue 12 Yellow STEP 3: Insert contact and wire into tool jaws. To crimp, squeeze handles together fully until ratchet releases and allows handles to expand; otherwise, contact cannot be extracted from tool jaws. Maintain slight insertion pressure on wire while crimping contact to wire. IMPORTANT NOTE: Microsection the contact to verify crimp quality. CONTACT INSERTIONAMPHENOL MB SERIES CONTACT INSERTION
STEP 1: Remove backshell and put wired contacts through cable clamp opening. STEP 2: Use colored end of CIET tool for insertion. Place wire into tool at large opening. To facilitate contact insertion, a six-inch minimum of free wire is recommended. STEP 3: Slide back tool on wire while holding thumb against wire at opening. Wire will slip into tool. STEP 4: With tool pressed against shoulder of contact, starting at the center cavity, insert wired contact and tool into properly-identified cavity at rear of plug with firm, even pressure. Do not use excessive pressure. STEP 5: When contact touches bottom, a slight click can be heard as tines of metal retaining clip snap into place behind contact shoulder. STEP 6: Check face of plug or receptacle for proper contact installation. In socket inserts with a large number of contacts, cavities are identified in a spiral pattern. A projecting line from the spiral indicates omission of a letter; a broken circle around a cavity indicates transition between capitals, and lower case and double letters. STEP 7: Withdraw tool from rear of plug. To be sure that contact is locked, pull back lightly on wire. Remove tool from wire and proceed with other contacts. STEP 8: After all contacts are inserted, fill unwired cavities with sealing plugs (insert head first and leave end protruding for ease of removal), assemble backshell on rear of connector.
CONTACT EXTRACTIONAMPHENOL MB SERIES CONTACT EXTRACTION
STEP 1: Remove backshell and slide back along wires to allow access. To extract a contact, use white end of CIET tool. Place wire into tool at large opening. Slide back tool on wire while holding thumb against wire at opening. Wire will slip into tool. STEP 2: Push tool into rear of plug until it touches bottom. At this point, tool releases tines on retaining clip so that contact can be extracted. STEP 3: While maintaining slight insertion force on tool, firmly hold wire against serrated shoulder at center of tool and extract both wired contact and tool from plug.
